Which of the following effects is least likely to be mediated by a scaffolding protein ? Increase the local concentration of sig
algol13

The correct answer is: Decrease allosteric effects and cooperative binding of second messengers to their targets.

Scaffold proteins are considered regulatory proteins that affect many signal pathways. Some of their functions are:

• Regulation and coordination of positive and negative feedback signals

• Localizing signal components within the cell (in different cell compartments)

• Tethering signaling components (assembling signal components into complexes in order to increase signal efficiency).

If a cell is able to synthesize 30 ATP molecules for each molecule of glucose completely oxidized to carbon dioxide and water, a
nadezda [96]

Answer:

The correct answer is - 14 OR 15 ATP.

Explanation:

At the end of the glycolysis, two molecules of the pyruvate produced in the cytoplasm which is followed by the pyruvate oxidation that takes place in the matrix of mitochondria in eukaryotes.

During the oxidation of the pyruvate, a carboxyl group is eliminated from the pyruvate and released as CO₂. Then the two carbon molecules oxidized produced in the first step and NAD+ accepts the electron and change into the NADH. The oxidized two carbon molecules attached to the coenzyme A and form acetyl CoA. This process generates 1 NADH which is equal to the 3 ATP.

During the TCA cycle, each molecule of the acetyl CoA oxidized to generate ATP  and carbon dioxide. This cycle produces 1 ATP, 1 FADH2, and 3 NADH. The total ATP production through this cycle is Approximately 12.

Thus, the correct answer is - 14 or 15 ATP.
