Cellular Respiration & Fermentation - CP

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 photosynthesis?

Back

The main purpose of photosynthesis is to convert light energy into chemical energy stored in glucose, using carbon dioxide and water.

Front

How do photosynthesis and cellular respiration relate to each other?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce ATP, while cellular respiration releases carbon dioxide and water, which are used in photosynthesis.

Front

What is glycolysis?

Back

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

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 (ETC)?

Back

The electron transport chain is the final stage of cellular respiration where electrons are transferred through a series of proteins, leading to the production of a large amount of ATP.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows cells to produce energy without oxygen, resulting in byproducts like lactic acid or ethanol.

Front

What is aerobic respiration?

Back

Aerobic respiration is a type of cellular respiration that requires oxygen to produce ATP from glucose.

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a type of cellular respiration that occurs without oxygen, producing less energy than aerobic respiration.

Front

What happens to breathing rate during exercise?

Back

Breathing rate increases during exercise to supply more oxygen to the muscles and remove carbon dioxide.
