12.5 - Mitochondrion Structure Flashcards
An overview of the structure of mitochondria How the structure of mitochondria relates to their functions
What is the function of mitochondria?
Site of aerobic cellular respiration
What type of cells have a higher number of mitochondria?
Metabolically active cells
What are the components of a mitochondrion?
Outer membrane
What is the function of the outer membrane?
Separates contents from the rest of the cell
What is the function of the intermembrane space?
Space where protons are pumped during oxidative phosphorylation
What is the function of the inner membrane?
Contains proteins for oxidative phosphorylation
What are cristae?
Folds in the inner membrane
What is the function of the matrix?
Site of link reaction and Krebs cycle
What is the function of mitochondrial DNA?
Codes for proteins required for function
What is the function of mitochondrial ribosomes?
Protein synthesis
What is the main function of mitochondria?
Produce ATP through oxidative phosphorylation
How does the matrix contribute to mitochondrial function?
Contains enzymes for link reaction and Krebs cycle
How do mitochondrial DNA and ribosomes contribute to mitochondrial function?
Produce proteins rapidly
How do cristae contribute to mitochondrial function?
Increase surface area for proteins
How does the intermembrane space contribute to mitochondrial function?
Allows rapid proton gradient buildup
