Adaptations of chloroplast and mitochondria

intermembrane space

Allows for the rapid accumulation of protons.

Inner Membrane

Contains the proteins of the electron transport chain and ATP synthase.

Cristae

The inner membrane has many folds, known as cristae, which increase surface area.

Matrix

Contains DNA, ribosomes, and all of the enzymes involved in respiration.

Thylakoid membrane

Contains chlorophyll for absorption of light.

Granum

flattened discs of thylakoid membrane which increase surface area.

thylakoid space

allows for the rapid accumulation of protons

Stroma

Contains DNA, ribosomes and all of the enzymes required for photosynthesis.
