Which statement is TRUE regarding the glycolytic pathway?

Westkost [7]

Answer:

d) All of the statements are true.

Explanation:

 It includes reactions catalyzed by three isomerase enzymes.

The statement is true because:

The first reaction which involve isomerase is the conversion of glucose 6-phosphate into fructose 6-phosphate with the help of an enzyme phosphoglucose isomerase.

The second reaction is conversion of dihydroxyacetone phosphate (DHAP) into glyceraldehyde 3-phosphate with the help of an enzyme triphosphate isomerase.

The 3rd reaction is conversion of 3-phosphoglycerate to 2-phosphoglycerate.

It includes five phosphate transfer reactions.

The statement is true because:

1. The conversion of glucoe to glucose 6-phosphate.

2. The conversion of fructose 6-phosphate to fructose 1,6-biphosphate.

3.The conversion of glyceraldehyde 3-phosphate to 1,3-biphosphoglycerate.

4. The conversion of 1,3-biphosphoglycerate to 3-phosphoglycerate.

5. The conversion of phosphoenol pyruvate to pyruvate.

It includes three enzymes that are regulated by product inhibition.

The statement is true because:

1. Hexokinase which is inhibited by its product glucose 6-phosphate.

2. Phosphofructokinase which is inhibited by ATP.

3. Pyruvate kinase which is also inhibited by ATP.

Thus, all the statements are correct.

When does the muscle repair process primarily occur?

a_sh-v [17]

Answer:

4-5 days

Explanation:

Muscle regeneration usually starts during the first 4–5 days after injury, peaks at 2 weeks, and then gradually diminishes 3 to 4 weeks after injury. It's a multiple steps process including activation/proliferation of SC, repair and maturation of damaged muscle fibers and connective tissue formation.

Sandra examined some animal cells using a compound microscope. Under normal conditions, the cells have an approximate salinity o

Greeley [361]

Answer:

If the cells are submerged in pure distilled water, each cell will absorb water from the environment where it is located, increase its volume and possibly break.

Explanation:

The cells maintain an osmotic balance relationship between their cytoplasm and the extracellular space, that is, the cell is isotonic with the medium.

When a cell is exposed to a hypotonic medium -such as that which provides pure distilled water- water will pass through osmosis from the extracellular space to the cytoplasm, causing the cell to increase in volume (swell) and the increase in internal pressure can Make it break.

In osmosis, water passes from space with less concentration of solutes to the highest concentration.

The cryosphere represents all living things a. true b. false

melisa1 [442]

False

Cryosphere can be defined as the portion of the earth’s where the water is in its solid form which includes lake ice, snow, ice caps, sea ice. Thus, cryosphere form an integral part of the global climate system and it overlap with the hydrosphere. Furthermore, the snow or ice areas are subjected to temperature below 320F for at least part of the year.
