Answer: c. Transition Reaction

Explanation:

During the transition reaction, Acetyl-CoA is formed and connects the first stage of glycolysis with the Krebs Cycle (Citric Acid Cycle). In the presence of oxygen, pyruvate enters the mitochondria and is oxidized to form a compound of 2 carbon, acetate, with energy and CO2 release. During this process, the acetate binds to a coenzyme(coenzyme A (CoA)) - forming the acetyl-coenzyme A.

The 3 steps:

1. pyruvate is oxidized and forms acetate with liberation of CO2;

2. the energy released in the oxidation of pyruvate is stored in the reduction reaction of NAD+ to NADH + H+

3. The acetate molecule combines with coenzyme A to form acetyl-coenzyme A.

Cells in a hypertonic solution tend to:
marshall27 [118]

Answer:

Shrink due to water loss

Explanation:

A hypertonic solution has more osmolarity than the cell. This causes the water inside the cell to go out since the osmolarities tend to equalize. And the cell does not allow the passage of other substances except water. Therefore the water will come out and the cell will shrink.  

In a hypotonic solution, the water will enter into the cell and in an isotonic solution the water will be moving into and out of the cell at the same rate.
