Comparing

Mitochondria

Bean shape

Colourless

Folded inner membrane

Develops first

present in cell of all types of aerobic organisms

The overall reaction its involved in is photosynthesis

Uses oxygen to produce ATP

Consumes oxygen

The two chambers are the matrix and cristae

Energy released by breaking down organic food, CO2 and H2O

Chemical energy sugar into ATP

Responsible for the catabolic reactions that release or uses energy

with the use of NAD

Has electron transport chain in the inner membrane of the mitochondria accepting electrons like NADH and FADH2

Electron carrier molecules are arranged in electron transport chains

Electron come from the splitting of water, which releases oxygen as a waste product or they come from the chloroplast electron transport chain

Electrons go between the two photosystems; photosystem I generating NADPH, photosystem II generating ATP

Chloroplast

Disc shape

Green in colour

Smooth inner membrane

Develops last

Present in green plants and green algae

The overall reaction its involved in is cellular respiration

Uses sunlight to produce glucose (ATP)

Releases oxygen

The two chambers are the stroma and thylakoid

Stored energy and uses CO2 and H2O to produce glucose

Solar/light energy into chemical energy sugar

Responsible for the anabolic reactions that requires energy to release energy

with the use of NADP

Has electron transport chain in the thylakoid membrane which accepts and pass along energy-carrying electrons

Electron carrier molecules are arranged in electron transport chains

Electrons come from glucose move through the electron transport chain towards oxygen, releasing energy at each step which is captured as ATP

Electrons go from a higher to a lower energy level and are ultimately passed to oxygen forming water
