respiration

Question 1

explain the process of oxidative phosphorylation

Answer 1

reduced NAS is oxidised and h+ ions are prosecuted in matrix of mitochondria, electrons are also released by reduced NAD. electors are passed along th electron transport chain were they release energy each tie the pass through sn electron carrier. the energy produced is used to uno h+ ions across membrane into intermembranw space, creating a proton gradient

Question 2

explain the process of chemiosmosis

Answer 2

the proton gradient caused by oxidative phosphorylation causes h+ to flw back though th embrace down a conc gradient, but due to the in permeability of the membrane to h+ ions they allow though atp synthase which catalyse the formation of atp from adp and pi
