Cellular Respiration: How Cells Release Energy

Cellular respiration primarily serves which purpose in living cells?

• To convert glucose into ATP, a usable energy form

• To store oxygen in the cytoplasm for later use

• To synthesize glucose from carbon dioxide and water

• To produce heat by breaking down proteins

Which balanced overall chemical equation best represents cellular respiration as described?

• C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

• C6H12O6 + CO2 → O2 + H2O + ATP

• 6CO2 + 6H2O → C6H12O6 + O2 + ATP

• C6H12O6 + O2 → CO2 + H2O (no ATP)

• Only in the nucleus

• Exclusively in the cell membrane

• Only in ribosomes

What role does ATP play in cells?

• It acts like a rechargeable battery powering cellular activities

• It is a waste product removed during respiration

• It stores genetic information like DNA

• It forms the cell’s structural support like the cytoskeleton

What event directly releases usable energy for the cell?

• Addition of a phosphate group to ADP

• Breaking one bond in ATP, converting it to ADP

• Oxidation of glucose to pyruvate

• Diffusion of oxygen into the cytoplasm

Which organelle is often called the 'powerhouse of the cell' due to its role in energy production?

• Chloroplast

• Mitochondria

• Golgi apparatus

• Nucleus

What is the main difference between aerobic and anaerobic respiration?

• Anaerobic respiration occurs only in plants

• Aerobic respiration requires oxygen, while anaerobic does not

• Aerobic respiration produces less ATP than anaerobic

• Anaerobic respiration uses sunlight as energy

Aerobic Respiration

• Break down glucose without oxygen

• Break down glucose with oxygen

• Making 2 ATP

• Occurs in the Cytoplasm
