Fall 24 - Cellular Respiration & Fermentation

What is the main purpose of cellular respiration?

• To convert carbon-based molecules from food and oxygen into ATP, which is used for energy.

• To break down ATP into carbon dioxide and water.

• To store energy in the form of glucose.

• To produce oxygen as a byproduct of energy production.

What is the difference between aerobic and anaerobic respiration?

• Aerobic respiration occurs without oxygen and produces less ATP.

• Anaerobic respiration requires oxygen and produces more ATP.

• Aerobic respiration requires oxygen and produces more ATP.

• Anaerobic respiration occurs with oxygen and produces less ATP.

What is ATP?

• A type of protein involved in cellular structure.

• A molecule that stores and transfers energy in cells.

• A carbohydrate that provides energy to cells.

• A lipid that forms cell membranes.

Where does cellular respiration occur in the cell?

• Nucleus

• Ribosomes

• Mitochondria

• Endoplasmic Reticulum

What is the role of oxygen in cellular respiration?

• Oxygen is used to convert glucose into ATP during aerobic respiration.

• Oxygen is a waste product of cellular respiration.

• Oxygen is not required for cellular respiration.

• Oxygen is used to break down proteins into amino acids.

Which types of cells perform cellular respiration?

• Only plant cells

• Only animal cells

• Both plant cells and animal cells

• Neither plant nor animal cells

What are the main products of cellular respiration?

• ATP, oxygen, and glucose

• ATP, carbon dioxide, and water

• NADH, carbon dioxide, and glucose

• ATP, ethanol, and water

What is the electron transport chain?

• A series of proteins in the inner mitochondrial membrane that transfer electrons and produce ATP through oxidative phosphorylation.

• A process that occurs in the cytoplasm to break down glucose into pyruvate.

• A mechanism for DNA replication that occurs in the nucleus of the cell.

• A type of cellular respiration that does not require oxygen.

What is the Krebs cycle?

• A series of chemical reactions in the mitochondria that produces ATP and electron carriers from pyruvate.

• A process that converts glucose into lactic acid in muscle cells.

• A pathway that synthesizes fatty acids from acetyl-CoA.

• A cycle that generates oxygen during photosynthesis.

What are electron carriers?

• Molecules that transport oxygen in the blood

• Substances that store genetic information

• Molecules like NADH and FADH2 that transport electrons to the electron transport chain

• Proteins that catalyze biochemical reactions
