theory of perfect competition

The following are some possible reference contents for the theory test of the Biochemical Theory and Experimental Skills Competition: ** I. Biological molecular structure and function ** 1. ** Nucleic acid ** - Nucleic acid was made up of a single unit, which was made up of a single nucleus and a single phosphorous acid. A single nucleus was made up of a single base and a single penose. Master the differences in the types of bases in different types of nuclear acid (DNA and DNA). For example, the bases in DNA are A, T, G, and C, while the bases in DNA are A, U, G, and C. - Nucleic acid structures included the primary structure (the order of arrangement of the nuclei) and the secondary structure (such as the double spiral structure of DNA, which was featured by anti-parallel, complementary pairing of bases, etc.). Understand the concepts of degeneration (such as heating to untangle the double-strand), renaturation (single strand re-forms the double-strand after degeneration), and molecular hybrids (hybrid double-strand formed by complementing the bases between different sources). - Among the physical and chemical properties of the nuclear acid, it had the property of ultraviolet-light absorption, and the maximum absorption peak was around 260mn. This characteristic could be used to carry out quantitative determination of the nuclear acid. 2. ** In terms of protein ** - A protein was made up of an acidic group. The general structural formula of an acidic group was that the central carbon atom was linked to an amine group, a starch group, a hydrogen atom, and a side chain group (R group). According to the difference in R groups, they could be divided into different types, such as non-polar and polar neutral. - Grasp the physical and chemical properties of the acid, such as the cleavage of the acid (it can be positively charged, negatively charged, or neutral under different pH-environments), and the equi-electric point (the pH-value when the net charge of the acid is zero). - The structure of a protein was divided into primary structure (the order of the arrangement of the protein, and the chain formed by the bond of the protein), secondary structure (including common structural forms such as alpha helices and beta-sheets, which were mainly maintained by hydrogen bonds), tertiary structure (the three-dimensional structure formed by the further folding of the protein chain on the basis of the secondary structure, which was maintained by a variety of chemical bonds), and tertiary structure (the spatial arrangement and interaction between the various submarines in the protein composed of multiple protein chains). - Understand the relationship between protein structure and function, such as the specific structural domains of some protein are related to specific functions, and the allosteric effect of protein (the combination of small molecules and protein causes its conformational changes and thus affects its function). ** II. Enzymology ** 1. The chemical nature of the protein was mainly protein, and a small number of them were also made up of DNA. The chemical structure of an protein included a protein and a cofactor. Some of them were active only when the protein was active, while others needed to be combined with a cofactor to be active. 2. In terms of the mechanism of the reaction, the reaction speed was increased by decreasing the activation energy of the chemical reaction. It had the characteristics of high efficiency and specific properties (absolute and relative). 3. The factors that affect the reaction include the concentration of the reagent, the concentration of the reagent, the temperature, the concentration of the reagent, the concentration of the reagent, the concentration of the reagent and the concentration of the reagent. Master the concept of the Michaelis-Menten constant (Km), which is the concentration of the substance when the reaction speed of the catalyze is half of the maximum reaction speed. It can reflect the affinity between the reagent and the substance. ** 3. Glycometabolization ** 1. glycogen metabolism - Glycogen cleavage is the process of decomposing the sugar residue from the non-reducing end of the glycogen. The key is the glycogen Phosphorase. Glycogen synthesis was the process of synthesizing glycogen from glucose, and the key was glycogen synthesis. 2. catabolic metabolism of glucose - The process of anaerobic decomposition (glycolysis) involves a series of zymic reactions that take place in the cell's plasma. The final product is either actic acid (in animals) or alcohol (in plants and microorganisms), which produces a small amount of ATP. - Aerobic decomposition (the fermentation of sugar) is divided into three stages: the glycolystic pathway, the decylating of methyruvate to form acety CoA, the tricarboxylic acid cycle, and the oxyphosphorification. The tricacid cycle was carried out in the mitochondria, which was the common pathway for the decomposition of sugar, fat, and protein. 3. Gluconeosis was the process of synthesizing glucose from non-sugar substances (such as methyruvic acid, actic acid, glycerine, etc.). It was mainly carried out in the liver. The key zymes were methyruvate carbolase, Phosphoenol-Pyruvate Carboxykinases, etc. ** 4. Biological Oxidation ** 1. Bio-oxidization refers to the process of the decomposition of substances in the body. It is a gradual process under mild conditions, and the energy is gradually released and can be effectively used. 2. The electron transfer chain was composed of a series of electron donating bodies in the mitochondria biological fermentation system. The order of the electron donating bodies was arranged from low to high according to the oxido-reduction potential. The energy released during the electron transfer process could be used to generate Ang. 3. The main ways to produce ATP-binding protein were to catalyze the protein at the level of the protein (directly producing ATP-binding protein during the fermentation of the protein) and to catalyze the protein (producing ATP-binding protein during the electron transfer process). ** V. Lipids metabolism ** 1. Lipids were divided into fats (tributylcerides) and fats (such as Phospholiptides, Choline, etc.). Fat mobilization referred to the process in which the fat stored in the fat cells was digested into gly cerol and fatty acid and released into the blood. The key was the hormone sensitive triglyerease. 2. Glycerol metabolism is mainly under the action of Glycerol Kinase to produce Glycerol- 3 -Phosphorate, which is then further oxided. Fatty acid fermentation includes beta-fermentation (carried out in the plasma and mitochondria, and each time it is decomposed, it will produce acety CoA, FADH <2>, and Phosphate-Phosphorase) and other processes. 3. Phospholipase metabolism involved the synthesis and decomposition of Phospholiptides. Choline synthesis was mainly carried out in the liver, and the main raw material for synthesis was Ac-CoA. Choline could be converted into important substances such as bile acid and steroid hormones. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Darwin's theory of biological evolution was not perfect. From the perspective of the theory itself, the core ideas included genetic variation and natural selection. In terms of genetic variation, with the development of modern genetics, people discovered more complex genetic mechanisms, such as the interaction of genes, epigenetics, etc. These were not known when Darwin proposed the theory of evolution, which showed the limitations of the theory to a certain extent. From the perspective of evidence, although a large number of fossil discoveries and genetic genetics research results supported the theory of evolution, there were still some disputes about the so-called " missing links." Although modern biologists had explained it from the perspective of evolutionary trees, this also reflected the challenges of the theory in explaining certain details of the evolutionary process. In the historical context of that time, Darwin's theory of evolution subverted traditional concepts such as species constancy. In the subsequent development process, modern science also continued to supplement and develop on its basis. For example, in the 21st century, based on the molecular clock, the protein PAM matrix and BLOSUM's aa matrix were used as evidence to continue to develop Darwin's theory of evolution on the basis of molecular genetics and evolutionary dynamics. This also showed that there was room for development in Darwin's theory of evolution, and it was not a perfect theory. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
