Cellular Respiration Basics

The process in which cells convert glucose into energy, primarily in the form of ATP.

A sugar molecule that serves as the primary fuel source for cellular respiration.

The powerhouses of the cell where cellular respiration takes place.

A high-energy molecule that acts as the primary energy currency for cells, storing energy in its phosphate bonds.

The first stage of cellular respiration where glucose is split into two pyruvate molecules in the cytoplasm.

A 3-carbon molecule produced during glycolysis, which then enters the mitochondria for further breakdown.

The second stage of cellular respiration, where pyruvate is broken down further, releasing carbon dioxide and generating energy carriers.

A process in the mitochondria where hydrogen ions are pumped across the inner membrane to generate ATP.

The inner membrane of the mitochondria, crucial for the electron transport chain and ATP production.

A form of respiration that occurs without oxygen, resulting in lactic acid or alcohol as byproducts.

Cellular Respiration is the process by which cells convert glucose into energy, which is primarily used in the form of ATP.

Glucose is a simple sugar that is a primary energy source for cellular respiration.

The mitochondria are the powerhouses of the cell because they carry out cellular respiration.

Aerobic respiration requires oxygen, while anaerobic respiration does not. During aerobic respiration, glucose is broken down to produce ATP and carbon dioxide and water as byproducts.

Anaerobic respiration produces ATP without oxygen, leading to the production of lactic acid or alcohol as byproducts.

ATP, or adenosine triphosphate, is the primary energy currency of cells, storing energy in its phosphate bonds.

Glycolysis is the first stage of cellular respiration, where glucose is broken down into two pyruvate molecules in the cytoplasm.

The Krebs cycle is the second stage of cellular respiration. In this stage, pyruvate is broken down further in the mitochondria, releasing CO2 and generating energy carriers like NADH and FADH2.

The Electron Transport Chain is the final stage of cellular respiration where ATP is generated. Hydrogen ions are pumped across the inner mitochondrial membrane, creating a gradient that drives ATP synthesis.

Cristae are folds in the inner mitochondrial membrane. They provide a large surface area for the Electron Transport Chain, increasing the rate of ATP production.
