8.2 Cell Respiration (extra)

Question 1

How is the structure of a mitochondria adapted to its function?

Answer 1

outer mitochondrial membrane - separates the contents of mitochondrion from rest of cell; makes it a compartment specialized for aerobic respiration;
inner mitochondrion membrane - site of oxidative phosphorylation (electron transport chains & ATP synthesis;
cristae - increase surface area vailable for xidative phosphorylation
intermembrane sapce - volume is small so concentration gradient builds rapid for ATP synthase
matrix - fluid contains enzymes to support reactions

Question 2
