Question

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

-Glucose
-ATP
-Pyruvate
-ADP
-G3P

Answer 1

During the last 5 steps of glycolysis, ATP, ADP, and Pyruvate are produced. These steps involve the phosphorylation without additional ATP investment and result in a net profit of 2 ATP and 2 NADH per glucose molecule.

Step-by-step explanation:

Select molecules that are produced during the second half (last 5 steps) of glycolysis: ATP, Pyruvate, and ADP. During these steps of glycolysis, a net profit of 2 ATP and 2 NADH are created per glucose molecule. Initially, glucose is split into two three-carbon compounds, and as the process continues, ATP is generated without additional investment of ATP (phosphorylation without ATP investment) and ultimately pyruvate is formed as the end product.

Here's a breakdown of the steps involved:

• Step 6: Glyceraldehyde-3-phosphate is oxidized, producing NADH and 1,3-bisphosphoglycerate.
• Steps 7 and 10: ATP is generated from ADP through substrate-level phosphorylation, producing a net gain of two ATP molecules.
• The final product of glycolysis is pyruvate, which is formed from the conversion of the high energy molecules during the last steps.
