Question

how is atp generated during the electron transport chain? a. by converting water into oxygen and hydrogen b. by using energy from electrons to pump protons and drive atp synthesis c. by breaking down glucose in the cytoplasm d. by combining pyruvate with oxygen what is the overall outcome of cellular respiration? a. the production of glucose and oxygen b. the storage of atp in the cytoplasm c. the breakdown of atp into glucose and water d. the conversion of glucose into atp, water, and carbon dioxide how does glycolysis contribute to cellular respiration? a. it breaks down glucose into pyruvate and generates a small amount of atp. b. it stores glucose for later use. c. it produces oxygen for the electron transport chain. d. it synthesizes proteins in the cytoplasm.

Explanation:

1. In the electron - transport chain, energy from electrons is used to pump protons across a membrane, creating a proton - motive force that drives ATP synthesis. Option b is correct for the first question.
2. Cellular respiration is the process of converting glucose into ATP, water, and carbon dioxide. Option d is correct for the second question.
3. Glycolysis breaks down glucose into pyruvate and generates a small amount of ATP. Option a is correct for the third question.

Answer:

1. b. By using energy from electrons to pump protons and drive ATP synthesis
2. d. The conversion of glucose into ATP, water, and carbon dioxide
3. a. It breaks down glucose into pyruvate and generates a small amount of ATP.
