Answer:

atp

Explanation:

ATP is composed of ribose, a five-carbon sugar, three phosphate groups, and adenine , a nitrogen-containing compound (also known as a nitrogenous base). What class of organic macromolecules is composed of monomers similar to ATP? ATP directly or indirectly delivers energy to almost all metabolic pathways.

Which of the following is a distinction between the Krebs cycle in eukaryotes and prokaryotes?
Flauer [41]

Answer:

C. The process occurs in the mitochondria of Eukaryotes.

Explanation:

  • In eukaryotes: glycolysis takes place within cytosol, Krebs cycle within mitochondrial matrix & ETC within inner mitochondrial membrane. Prokaryotes undergo binary fission(only cytokinesis) & conjugation.
  • Prokaryotes undergo binary fission(only cytokinesis) & conjugation. Eukaryotes perform mitosis, meiosis(both karyokinesis and cytokinesis).

Therefore in prokaryotic cells, the citric acid cycle occurs in the cytoplasm; in eukaryotic cells, the citric acid cycle takes place in the matrix of the mitochondria.

Acetyl-CoA reacts in the first step of the eight step sequence of reactions that comprise the Krebs cycle, all of which occur inside mitochondria of eukaryotic cells. While the Krebs cycle does produce carbon dioxide, this cycle does not produce significant chemical energy in the form of adenosine triphosphate (ATP) directly, and this reaction sequence does not require any oxygen. Instead, this cycle produces NADH and FADH2, which feed into the respiratory cycle, also located inside of the mitochondria. It is the respiratory cycle that is responsible for production of large quantities of ATP and consumption of oxygen. In addition, the respiratory cycle converts NADH and FADH2 into reactants that the Krebs cycle requires to function. Thus, if oxygen is not present, the respiratory cycle cannot function, which shuts down the Krebs cycle. For this reason, the Krebs cycle is considered an aerobic pathway for energy production.

Hope this helps!

Viral infection will provoke cell mediated immunity but will not activate a humoral response.
DiKsa [7]
This statement is false. <span> The humoral immune system is one part of the immune system that is activated when pathogens are present in the blood stream or other body fluids. B cells are the main cells involved in the response, and these cells secrete antibodies that seek out and attach to pathogenic molecules. These attached antibodies act as markers, marking the pathogens for destruction by other parts of the immune system.</span>

The movement of materials through the channel protein that does not require energy:
Zinaida [17]

Answer: Passive processes.

Explanation: Passive processes don't require the cell to expand any of its own energy in order to move. There are two types of passive processes: osmosis and diffusion. Diffusion is higher to lower, while osmosis is lower to higher.

What would happen to the DNA molecule if the pairing was non-complementary, in other words, the two purines (adenine and guanine
7nadin3 [17]

If the base-pairing in DNA becomes non-complementary such that purine bases can pair with one another and pyrimidine bases can pair with one another, the 1:1 ratio of purine to pyrimidine bases in DNA will no longer hold.

Due to the complementary base-pairing rule, the ratio of purine to pyrimidine bases in DNAs is usually 1:1. This is because Adenine always pairs with Thymine while Guanine always pairs with Cytosine.

Once this base-pairing rule is removed and becomes purine-purine and pyrimidine-pyrimidine pairings, then it becomes unnecessary for the ratio of purine to pyrimidine bases to be 1:1.
