Oxidative Phosphorylation Flashcards
What do the hydrogen and electron act like in op
They are valuable sources of energy hydrogen atoms are carried by fad and nad into the oxidative phosphorylation
What is the first step of the electron carrier chain what happens to the nadh
it releases the hydrogen and then oxidised to nad which is returned to the krebs cycle
What does the fadh do
it attaches to a protein further along the respiratory chain and h split into hydrogen ion and electrons
What happens to the electron
They are passed along the electron carrier protiens found on the membrane chain releasing energy
what is the released energy used for
used for active transport to actively transport hydrogen atoms from the matrix to the inner membrane space creating a concentration gradient
What happens to the accumulated protons
They can only diffuse through the atp synthase channel provideing energy for adp and pi to react to form atp
What happens once the protons are back in the matrix
oxygen is used as the terminal acceptor and combine with hydrogen ions and electron to form water and to maintain gradient
what happens if there is an absence of oxyen
the electron transport chain stops as there is no oxygen to accept them
why does fad result in less yield
as it does not provide as much energy to pump hydrogen ions into the intermembranal space
