CELL BIO: CH. 14: ENERGY GENERATION IN MITOCHONDRIA AND CHLORPLASTS

evidence of endosymbiotic theory

own DNA, reproduce like bacteria, ribosomes, double membrane

how do mitochondria and chloroplast divide

binary fission

what is the name for when multiple endosymbiotic organelles join together

fusion

true or false: more mitochondrial are found where more energy is needed

true (heart cells or neurons that are used a lot have more mitochondria)

the membrane of the mitochondria sets up what

gradient

Proton Gradient

a gradient formed by the difference in proton concentrations across a membrane

How does oxidative phosphorylation work?

Occurs in the mitochondria and is the mechanism by which energy of electrons dropped off by electron carriers is red to pump protons from low to high across a membrane which is coupled with the creation of ATP by powering ATP synthase to push together ADP and P

what are the required components of oxidative phosphorylation

membrane, proton pump, ATP synthase, source of high energy electrons and protons
