Question

15. Which of these molecules completes the process of cellular respiration?
glucose + oxygen ----> water +
A. ATP, carbon dioxide
B. ADP, oxygen
C. NADH, oxygen
D. oxygen, ADP​

Answer 1

Answer:

D oxygen, ADP

Answer 2

$glucose + oxygen --> water + carbon dioxide + ATP$

Explanation:

Cellular respiration is a biological process in which matter and energy flows through the biosphere.

• Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.

• Cellular respiration occurs in mitochondria of living organisms.

• It breaks down sugar in the presence of oxygen for releasing energy in the form of ATP.

• Electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step. It happens to capture this energy in the form of ATP.

• ATP is  adenosine triphosphate, it is a kind of currency for energy. It is the principal molecule for storing and transferring energy in cells.
