Answer 1

Glycolysis consists of priming reactions that use 2 ATP, cleavage to form two 3-carbon sugars, and oxidation that produces 4 ATP and 2 NADH.

Step-by-step explanation:

The process of glycolysis involves multiple steps and consumes and generates various reactants and products at each stage:

• Priming Reactions: Use 2 ATP (b) to prepare the six-carbon ring of glucose for cleavage into two three-carbon sugars.
• Cleavage: Generate two 3-Carbon sugars (g).
• Oxidation: Produce 4 ATP (c) and 2 NADH (d) through the oxidation of glyceraldehyde-3-phosphate, with 2 NAD+ being utilized in the process (f).

Glycolysis starts by using ATP to phosphorylate glucose, a process requiring energy investment. As the pathway progresses, ATP and NADH are produced, resulting in a net gain of energy carriers for the cell. Glycolysis is organized in a way that the initial energy investment yields a greater return by the end.
