What is the role of ATP synthase in cellular respiration?

Back

ATP synthase is an enzyme in the electron transport chain (ETC) that synthesizes ATP from ADP and inorganic phosphate during oxidative phosphorylation.

Front

What process occurs after glycolysis if oxygen is not present?

Back

Fermentation occurs after glycolysis in the absence of oxygen, allowing cells to produce energy anaerobically.

Front

During which process is glucose broken down?

Back

Glycolysis is the process where glucose is broken down into pyruvate, producing a small amount of ATP.

Front

What are the end products of glycolysis?

Back

The end products of glycolysis are 2 molecules of pyruvate, 2 ATP, and 2 NADH.

Front

What happens to energy production when oxygen levels decrease?

Back

A decrease in oxygen availability decreases the amount of energy produced during cellular respiration.

Front

What is the main purpose of cellular respiration?

Back

The main purpose of cellular respiration is to convert biochemical energy from nutrients into ATP, and then release waste products.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration that breaks down glucose into two molecules of pyruvate, occurring in the cytoplasm.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows cells to generate energy without oxygen, producing lactic acid or ethanol as byproducts.

Front

What is the Krebs cycle?

Back

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

Front

What is the electron transport chain?

Back

The electron transport chain is a series of protein complexes located in the inner mitochondrial membrane that transfer electrons and pump protons to create a proton gradient for ATP synthesis.
