[ Mitochondrion Structure ] - IB Bio Topic 8.2 Cell Respiration

What is the function of the Inner mitochondrial membrane?

Contains electron transport chains & ATP synthase

What is the function of the matrix?

Contains enzymes for Krebs cycle & link reaction

What is the function of the Ribosome DNA?

Controls expression of mitochondrial genes

How can the 3D structure of a mitochondria be obtained?

Electron tomography

What is the function of the Cristae?

Increase surface area available for oxidative phosphorylation

What is the function of the Intermembrane space?

Intermembrane space provides a small space for the concentration of proteins pumped into space by electron transport to build up quickly

What is the function of the outer mitochondrial membrane?

Separates contents of cell from rest of cell and creates cellular compartment w/ ideal conditions for aerobic respiration
