Question

Choose molecules that are produced during the second half (last 5 steps) of glycolysis.

A) NADH
B) Glucose
C) ATP
D) Pyruvate

Answer 1

In the second half of glycolysis, the molecules produced are NADH, ATP, and Pyruvate. NADH is generated during the oxidation of glyceraldehyde-3-phosphate, ATP is produced with a net gain of two per glucose molecule, and Pyruvate is the end product of glycolysis.

Step-by-step explanation:

During the second half of glycolysis, several key molecules are produced as the pathway proceeds towards the production of pyruvate. The second half of glycolysis, also known as the energy-releasing steps, focuses on converting the energy stored in glucose into forms that can be utilized by the cell.

The specific molecules produced in this phase include:

1. NADH - This molecule is generated during step 6, where glyceraldehyde-3-phosphate is oxidized and a high-energy electron is transferred to NAD+, forming NADH.
2. Pyruvate - The end product of glycolysis is pyruvate. Each molecule of glucose, through a series of steps, is ultimately broken down into two molecules of pyruvate

Considering the choices given, molecules that are produced during the second half of glycolysis include NADH, ATP, and Pyruvate. Glucose is the starting molecule of glycolysis and is not produced during this process.
