48) For each pair of electrons carried by NAD down the electron transport system, how many hydrogen ions (H+) are pumped from the mitochondrial matrix into the intermembrane space?
a) 2 b) 4 c) 6 d) 10 e) 12
d) 10

a) 2 b) 3 c) 4 d) 8 e) 10
c) 4
56) The synthesis of ATP during cellular respiration may occur via two processes. List and describe them. (4 pts.)
Substrate level phosphorylation: involves direct transfer of a phosphate group from a substrate molecule to ADP, forming ATP.
Oxidative phosphorylation: involves the electron transport chain. synthesizes ATP from ADP phosphate.
57) What is the specific function of each of the following enzymes? (4 pts.)
a) Isomerase
b) Decarboxylase
c) Kinase
d) Dehydrogenase
a) Isomerase: converts one isomer to another.
b) Decarboxylase: removes a carboxyl group from a substrate.
c) Kinase: transfers phosphate group to a substrate.
d) Dehydrogenase: removal of hydrogen atoms from a molecule.
how many H+ pass through the mitochondria matrix?
6
List and describe the three major stages of the Calvin Benson cycle (6pts)
(63)
(64)
(65)
(63) carbon fixation: CO^2 is taken from air and attached to the 5 carbon molecule that creates a 6 carbon molecule which splits to a 3 carbon molecule.
(64) Reduction: plant uses energy from ATP and NADPH to change 3 carbon to G3P
(65) regeneration: some G3P are used to make sugar the rest help the cycle start over.
(62) The light reactions are initiated when_____ molecules within photosystem II absorbs_______ and this results in the excitation of electrons. the electrons that are produced are extracted from a ________ molecule to ultimately produce_______ gas. Two electrons pass from the primary electron acceptor II to photosystem I via a series of electron carriers, these electron carries comprise the _______. NADP+ reductase transfer the two electrons from ferredoxin to the coenzyme,______ to produce______, one of the two forms of chemical energy produced during the light reactions.
The light reactions are initiated when -chlorophyll- molecules within photosystem II absorb -light- and this results in the excitation of electrons. The electrons that are produced are extracted from a – -water- molecule to ultimately produce -oxygen- gas. Two electrons pass from the primary electron acceptor II to photosystem I via a series of electron carriers, these electron carriers comprise the ————electron transport chain–. NADP+ reductase transfers the two electrons from ferredoxin to the coenzyme, -NADP+-, to produce –NADPH,– one of the two forms of chemical energy produced during the light reactions.
