how many Krebs are there per molecule of glucose?
2
which phases of respiration involve substrate level phosphorylation?
Glycolysis, Krebs, Link
what does the 6 carbon glucose molecule turn into in glycolysis?
2 x 3 carbon pyruvate
how many molecules of ATP are yielded per molecule of glucose in anaerobic respiration?
2
where is the electron transport chain?
cristae
what product is formed in plant cells in anaerobic respiration?
ethanol
how many molecules of FADH2 are made per Krebs cycle?
2
where does glycolysis take place?
in the CYTOPLASM
how many molecules of NADH2 are made in glycolysis?
2
where does glycolysis take place?
in the CYTOPLASM of the cell
is glycolysis aerobic or anaerobic?
anaerobic
what is the yield of glycolysis?
4 ATP (2 nett) 2 NADH
how does the pyruvate go into the mitochondrion for the link?
active transport
what reaction turns glucose to GP and hexose biphosphate?
phosphorylation (ATP goes to ADP)
what reaction turns TP pyruvic acid?
oxidation ( loss of hydrogen to make NAD into NADH)
where does the link reaction take place?
the mitochondrial matrix
what are the products of the link reaction?
2 CO2 and 2 NADH per glucose
describe the link reaction
pyruvate is dehydrogenised and decarboxylated to form acetate, acetate combines with coA to form actetyl coA
what is dehydrogynation?
loss of hydrogen (H+)
what is decarboxylation?
loss of carbon atom
where does the krebs cycle happen?
mitochondrial matrix
how is the 6 carbon compound formed?
acetyl coA (2 carbon) combines with a 4C compound
draw out krebs and check against notes
(insert picture)
what is substrate level phosphorylation?
creation of ATP without ATP synthase, phosphate is added from another molecule
what are the products of the krebs cycle? (per cycle)
3 x NADH, 1 x ATP, 1 x FADH, 2 x CO2
where does oxidative phosphorylation take place?
cristae
describe oxidative phosphorylation
e- and H+ are released from reduced coenzymes (eg) NADH), electrons flow along the ETC in a series of redox reactions, electrons release energy that pumps H+ into the intermembrane space, H+ flow down the proton gradient through ATP Synthase which phosphorylate ADP to make ATP. O2 is the final electron accepter and makes water.
