The following chemical reactions in human cells must be carried out in the organelles

The condition of the question is that human beings are eukaryotic organisms in terms of human cells.

B: ATP is formed in the cytoplasm (the first stage of aerobic respiration and the entirety of anaerobic respiration).

c: mRNA synthesis is mainly synthesized in the nucleus, and can also be synthesized in the cytoplasm and within the mitochondria.

D: Amino acids are dehydrated and condensed to form peptide bonds, so the formation of peptide bonds is done on ribosomes.

So the correct answer is ad

I choose ぀The consumption of oxygen is aerobic respiration, eukaryotic aerobic respiration is ** on the chondria, prokaryotes do not have mitochondria, but they can also carry out aerobic respiration, relying on enzymes related to aerobic respiration in the cytoplasmic matrix, which is carried out in the cytoplasmic matrix.

The generation is mainly photosynthesis and respiration, and the anaerobic respiration of respiration takes place in the cytoplasmic matrix.

It is a product of DNA transcription, and the transcription of DNA mainly takes place in the nucleus, which is not an organelle.

A: In eukaryotes that undergo aerobic respiration, the consumption of oxygen occurs on the ** partichondria, which is the third stage of aerobic respiration, which combines with reduced hydrogen to produce water; , but the oxygen consumption of prokaryotes that carry out aerobic respiration is cytoplasmic.

B::ATP is formed in the cytoplasm (the first stage of aerobic respiration and all of anaerobic respiration).

C: mRNA synthesis, which is synthesized under the action of RNA polymerase, is located in the cytoplasm;

D: Peptide bond formation is done on ribosomes.

So choose D

a, oxygen is consumed in many places, not only mitochondria.

d, only in ribosomes. Pick D

Cyanobacteria are prokaryotic cells with no chlorophyll bodies, and the fixation of carbon dioxide in photosynthesis is carried out on the photosynthetic sheet; The formation of viral nucleic acids, the transcription of the megatype family takes place in the nucleus or in the cytoplasm, and the nucleus is not an organelle; Peptide bonds are formed on ribosomes.

Answer: AK+

Under normal circumstances, the transmembrane mode of transport pants is an active transport sail barricade, and when the concentration is in order, it may be to assist the Hu sedan to take the diffusion; So option A is wrong.

Answer: Thorough oxidation of pyruvate is carried out in the ** granula; The synthesis of various digestive enzymes is carried out in ribosomes; The breakdown of propium ketoate by E. coli is carried out in the cytoplasmic matrix; The fixation of carbon dioxide is carried out in chloroplasts. Therefore, C is selected for this question. Stupid.

Anaerobic respiration in the cytoplasm So choose A

Proteins are produced by ribosomes that endoplasmic reticulum is processed by the Golgi apparatus.

Insulin belongs to the protein ribosomes produced by the endoplasmic reticulum and processed by the Golgi apparatus and excreted by the cell membrane.

a. Many important chemical reactions in the cell are carried out on the biofilm, which is one of the functions of the biofilm, a correct;

b. Since the structure determines the function, the local mode is this, so the structural connection of various biological Tongxun membranes is a prerequisite for the functional connection, B is correct;

c. Prokaryotic cells and mammalian mature erythrocytes have only cell membranes, and C is wrong;

d. The orderly progress of a series of enzymatic reactions of the biofilm on the cell and the regionalization of the whole cell provide the conditions for the lead to be correct

Therefore, c

Option D, whether prokaryotic cells or eukaryotic cells must be carried out on ribosomes, anaerobic respiration in item A and aerobic respiration of prokaryotic cells are not in organelles, cyanobacteria and nitrifying bacteria are not in organelles when they are carried out, and nitrifying bacteria in item C are not in organelles.

Answer B Organisms are always constantly exchanging substances with the external environment, selectively taking various substances from inorganic nature to compose themselves, whether they are the same organisms or different organisms, the types of chemical elements that make up their cells are roughly the same, but the content of various elements that compose them is different, so they can be divided into macroelements and trace elements. All the elements that make up living organisms are found in inorganic nature, and there are no elements specific to cells. Sun Tangerine.

Answer] A Answer Analysis] Test Question Analysis: In the cells of lower plants (such as Algae), there can be chloroplasts and centrosomes at the same time, a is correct; The DNA in the cell of the apical meristem of the onion is present in the mitochondria and nucleus, which has no chloroplasts, B error; Ribosomes have no membrane structure, and the Golgi apparatus is a monolayer membrane structure, c error; There may be ** mitochondria in living cells, or there may be no mitochondria in the stool, d error.
