Cellular Respiration

Front

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

What is the main purpose of ATP in cellular respiration?

Back

ATP (adenosine triphosphate) serves as the primary energy currency of the cell, providing energy for various cellular processes.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration, where one molecule of glucose is broken down into two molecules of pyruvic acid, producing a small amount of ATP.

Front

What are the end products of glycolysis?

Back

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

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP through oxidative phosphorylation.

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.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the process of ATP production that occurs in the electron transport chain, driven by the flow of protons back into the mitochondrial matrix.

Front

What is lactic acid fermentation?

Back

Lactic acid fermentation is an anaerobic process that occurs in muscle cells when oxygen is scarce, converting pyruvic acid into lactic acid and producing ATP.

Front

What is the chemical equation for cellular respiration?

Back

C6H12O6 (Glucose) + O2 (Oxygen) -> CO2 (Carbon Dioxide) + H2O (Water) + ATP.

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.
