Question

1. what does the body need to start cellular respiration? 2) what are the 3 major steps of cellular respiration? (a)__ (b) (c)__ 3) what can be produced from nadph? 4) how many atp can be produced from one glucose molecule?

Explanation:

Step1: Identify requirements for cellular respiration

The body needs glucose and oxygen to start cellular respiration.

Step2: Name the 3 major steps

The 3 major steps of cellular respiration are glycolysis, the citric - acid cycle (Krebs cycle), and oxidative phosphorylation.

Step3: Products from NADPH

NADPH is mainly involved in photosynthesis, not directly in the main products of cellular respiration. In cellular respiration, NADH is more relevant and is used to produce ATP during oxidative phosphorylation.

Step4: Calculate ATP from glucose

Approximately 30 - 32 ATP can be produced from one glucose molecule through cellular respiration.

Answer:

1. Glucose and oxygen
2. Glycolysis, Citric - acid cycle (Krebs cycle), Oxidative phosphorylation
3. NADPH is mainly for photosynthesis; in cellular respiration, NADH is more relevant and used to produce ATP in oxidative phosphorylation
4. 30 - 32 ATP
