Mitochondrial Structure and Function

Mitochondrial structure refers to the double-membrane organelle containing inner folds called cristae, which house the electron transport chain and ATP synthase, essential for cellular respiration. Its primary function is to generate adenosine triphosphate (ATP) through oxidative phosphorylation, utilizing nutrients and oxygen to produce energy for cellular activities.

Overview

Mitochondria are essential organelles found in nearly all eukaryotic cells, primarily responsible for producing ATP through cellular respiration. Their unique double-membrane structure, featuring an inner membrane folded into cristae, maximizes the surface area for energy production processes. The m...

Key Terms

Mitochondria
Organelles that produce energy in cells.

Example: Mitochondria are often called the powerhouses of the cell.

ATP
Adenosine triphosphate, the energy currency of the cell.

Example: Cells use ATP to power various functions.

Glycolysis
The process of breaking down glucose to produce energy.

Example: Glycolysis occurs in the cytoplasm before entering mitochondria.

Krebs Cycle
A series of reactions in mitochondria that produce energy carriers.

Example: The Krebs cycle is crucial for aerobic respiration.

Electron Transport Chain
A series of proteins in the inner mitochondrial membrane that generate ATP.

Example: The electron transport chain is the final step of cellular respiration.

Cristae
Folded inner membrane of mitochondria that increases surface area.

Example: Cristae are where ATP production occurs.
