What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

How is cellular respiration related to photosynthesis?

Back

Respiration is the opposite of photosynthesis; while photosynthesis converts carbon dioxide and water into glucose and oxygen using sunlight, respiration breaks down glucose and oxygen to produce energy.

List the stages of Cellular Respiration in order.

Back

1. Glycolysis (D) 2. Pyruvate Oxidation (B) 3. Citric Acid Cycle (E) 4. Electron Transport Chain (C) 5. Chemiosmosis (A)

Front

What is the correct equation for cellular respiration?

Back

6O2 + C6H12O6 -> 6CO2 + 6H2O + Energy

Front

What is chemiosmosis?

Back

Chemiosmosis is the movement of H+ ions across a membrane, which generates ATP as they pass through ATP synthase.

Front

What is the role of ATP synthase?

Back

ATP synthase is an enzyme that synthesizes ATP from ADP and inorganic phosphate using the energy from H+ ions moving down their concentration gradient.

Front

What are stomata?

Back

Stomata are small openings on the surface of leaves that allow gases (such as CO2 and O2) to enter and exit the leaf.

Front

What is the function of the electron transport chain?

Back

The electron transport chain is a series of protein complexes that transfer electrons and pump H+ ions to create a proton gradient for ATP production.

Front

What is glycolysis?

Back

Glycolysis is the first stage of cellular respiration that breaks down glucose into two molecules of pyruvate, producing a small amount of ATP and NADH.

Front

What is the citric acid cycle?

Back

The citric acid cycle (Krebs cycle) is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.
