ATP Flashcards
1
Q
What is chemiosmosis
A
flow of protons down an electrochemical gradient through ATP synthetase coupled with synthesis of ATP from ADP+pi
2
Q
how are mitochondria and chloroplasts similiar
A
both create a proton gradient by only letting protons across
protons easily pass through water so they have to be water tight and are known as sealed membranes
3
Q
how are proton gradients maintained
A
by proton pumps and energy from excited electrons
4
Q
how is disrupting proton gradients dangerous
A
preventing proton gradients causes apoptosis
DNP allows electron transport but not ATP synthesis body oxidises fats and carbs and all energy released as heat
5
Q
what is an electron transport chaim
A
series of protein carriers on inner membranes of mitochondria and chloroplast
