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 are the three main stages of aerobic respiration?

Back

The three main stages of aerobic respiration are Glycolysis, Kreb's Cycle, and Electron Transport Chain (ETC).

Front

What is Glycolysis?

Back

Glycolysis is the first step of cellular respiration that occurs in the cytoplasm, where glucose is broken down into pyruvate, producing a small amount of ATP.

Front

Where does the Kreb's Cycle occur?

Back

The Kreb's Cycle occurs in the mitochondria of the cell.

Front

What is the main purpose of the Kreb's Cycle?

Back

The main purpose of the Kreb's Cycle is to produce electron carriers (NADH and FADH2) that are used in the Electron Transport Chain.

Front

What is the Electron Transport Chain (ETC)?

Back

The Electron Transport Chain (ETC) is the final stage of aerobic respiration, occurring in the inner mitochondrial membrane, where ATP is produced using the energy from electrons.

Front

What are the two reactants of cellular respiration?

Back

The two reactants of cellular respiration are glucose (C6H12O6) and oxygen (O2).

Front

What are the two products of aerobic respiration?

Back

The two products of aerobic respiration are carbon dioxide (CO2) and water (H2O).

Front

How much ATP is produced in aerobic respiration?

Back

Aerobic respiration can produce up to 36-38 ATP molecules from one molecule of glucose.

Front

What is fermentation?

Back

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