On a few topics about biochemistry, please help me

Multiple choice question 1 is that the order of the bases on the mRNA should determine the primary structure of the protein.

Question 2 fill-in-the-blank question is indeed 4 Note that it says "consuming high-energy phosphate bonds".

The activation of AA consumes 2 high-energy phosphate bonds, although it uses an ATP but it.

Two ppi are removed, so two high-energy phosphate bonds are consumed.

Add the two GTPs of carry and shift and that's 4.

True/False Question 1 I remember that there are more than 10 ...... of eukaryotic priming factorsThe elongation factor is less than the prokaryotic termination factor.

Just one. Multiple choice question 2 C. Related to the entry of peptidyl-tRNA into site A Did you write it wrong? The A position is the aminoacyl position.

Will it be peptidoyl-tRNA advancement?

True/False Question 2: I don't think there is a direct connection between the faithfulness of the translation and the activity of gtpase......Is this question true? It's boring......

True/False Question 3 There is such a question: How much ATP does it take to synthesize 600 amino acids?

The answer is 2400, which is 7+598x4+1

Starting complex: 1 GTP

Formylmethionine was activated 2 pcs.

2 new AA activations.

Carry 1. Shifted 1 pcs.

From thereafter, each AA consumes 4 high-energy phosphate bonds.

Pull the plug. None of activation, none of carrying, and no displacement.

The peptide chain is detached by 1gtp

Ubiquitin is explained to proteins, and after adding a specific signal to one end of the protein, it is explained, and ATP is consumed

24.The conjugated enzyme exhibits an active strip that is present in the form of a holoenzyme

25.The ligands that affect ion channel switching are mainly (a neurotransmitter).

28.When measuring enzyme activity, in the reaction system, the correct statement is that (some enzymes need to be added with an activator).

32.Swing pairing refers to which of the following bases is not strictly paired (B anticodon third base vs. codon first base).

33.The proteolytic enzymes that belong to exopeptidases are (B carboxypeptidase).

34.The concept of "gene expression" is mistaken (a, the process always goes through the process of gene transcription and translation).

36.The isoelectric point of the protein is (c.).The protein molecule is a facultative ion, and the pH of the solution when the net charge is zero).

37.The amino acid containing two carboxyl groups is (C aspartic acid).

38.The narrative about or lettering exons and introns is correct (the process of removing introns is called splicing).

I have forgotten a lot about biochemistry I used to study, but that's all I have for now!

FDNA, FDNB, chymotrypsin, trypsin (T), CNBR these reagents can be found in peptide bai

The specific position of the chain degrades the polypeptide, and according to the product of their action, it can be speculated what amino acid is above or below the product, so that the amino acid order of the polypeptide can be known together. As for the specific sites of action of these reagents, please check it out for yourself...

1.I won't talk about bai in the previous sentence

All three will be converted into acetyl CoA to participate in the DAO tricarboxylic acid cycle, so it is a common metabolic pathway, a special sugar (

Lipid proteins) can be thoroughly oxidized through the tricarboxylic acid cycle to generate NADH acetylCoa, etc. As a raw material for the synthesis of proteins (sugars), it can be used as a channel for the mutual transformation of the three. (This question is the metabolic relationship between the accounting and the other three types of substances).

2.The liver is an important organ for detoxification, and the intake of large amounts of protein, and the inability to transaminate due to reduced aminotransferase activity may lead to an increase in ammonia concentrations in the blood. (in this regard).

3. The first-level structure is the foundation of the high-level structure. The higher order structure determines the activity and the primary structure determines the function (around these two points).

Question D, methionine contains S, but it is a non-polar amino acid. The second question D, adds, where the A chain also has an intrachain disulfide bond. Question 3C, the lungs contain more LDH3, and the serum LDH3 can often be elevated in lung diseases.

LDH3 and LDH4 are equal in pulmonary infarction, and LDH1 decreases significantly; Serum LDH3 and LDH4 are often elevated at the same time as LDH5 in patients with lung abscess. (This one is a bit uncertain). Question D, the glucose formed by glucose-6-phosphatase in the liver, intestine and kidney enters the bloodstream and catalyzes the hydrolysis of glucose-6-phosphate into glucose.

But this enzyme is not present in the brain and muscles. Question 5c, which produces 1 molecule of FADH2, and 1 molecule of NADH, is equivalent to 5 molecules Question 6. Potato pomace Question 7, this enzyme is called acetylacetyl synthetase in our book.

Question 8: Cholesterol is the raw material of bile acids synthesized in the liver. Bile is one of the essential digestive juices for digesting and absorbing fats, and the main component of bile is bile acids, and the main component of bile acids is cholesterol. Question 9 is produced by glutamic acid decarboxylation.

Question 10 Phenylalanine is an essential amino acid and cannot be synthesized in the body.

Wow, it took me an hour and a half to look up the book, I think it's good, please correct any mistakes!

1 Base pairing ensures the stability of the DNA replication process, so that the genetic material can be accurately transmitted.

2. Ensure the stability of replication.

3 The genetic code is universal and degeneracious, and three codons encode an amino acid4 Sugars, fats, amino acids, etc. in living organisms are thoroughly oxidized and decomposed into CO2 and NADH through the tricarboxylic acid cycle, and oxidative phosphorylation is carried out through the four complexes on the respiratory chain, and the electrons on NADH are handed over to the final acceptor O2 of the respiratory chain to generate water, and in the process of electron transfer, complexes 1, 3, and 4 will pump H protons, produce proton gradients, and promote the operation of ATP synthase, Produces a large amount of ATP (if entering from complex 1, it will produce ATP, if entering from complex 2, it will produce ATP).

1. The main significance of base complementary pairing is to ensure the accuracy of genetic information in the transmission process 2. Only every three adjacent bases on the messenger RNA are called codons, which are transcribed from genes and have degeneracy, with a total of 64, of which 3 stop codes do not code amino acids.

3. Carbon dioxide is mainly a product of cellular respiration, in which aerobic respiration completely oxidizes and decomposes glucose to form carbon dioxide and water.

Anaerobic respiration can produce alcohol and carbon dioxide. The process of forming proteins in ribosomes also produces water.

The main forms of ATP are cellular respiration and photosynthesis.

1.It is conducive to maintaining the stability of biological genetic information, and is conducive to the transcription and translation of biological genetic information.

2.It is beneficial to keep the offspring DNA consistent with the parental DNA, so that the genetic information of the organism remains stable.

3.Degeneracy, specificity.

4.Aerobic respiration produces carbon dioxide, water, and a large amount of ATP, anaerobic respiration produces carbon dioxide, lactic acid, and a small amount of ATP, and some organisms produce alcohol from anaerobic respiration.
