requires oxygen and produces CO2, water and much ATP
1 of 15
anaerobic respiration...
takes place in the absence of oxygen and produces lactate( in animals) and or ethanol and CO2 in plants. In both cases only a little ATP is produced.
2 of 15
what is the overall yield from one glucose molecule undergoing glycolysis?
two ATP, two molecules of reduced NAD and two molecules of pyruvate.
3 of 15
what is the link reaction?
pyruvate + NAD + CoA --> acetyl CoA + reduced NAD + CO2
4 of 15
for each molecule of pyruvate, the link reaction and the krebs cycle produce...
one ATP, reduced coenzymes (which have the potential to produce ATP) and three molecules of CO2
5 of 15
where do the link reaction and the krebs cycle occur?
In the matrix of the mitochondria
6 of 15
where does glycolysis occur?
in the cytoplasm
7 of 15
what are coenzymes?
molecules that some enzymes require in order to function.
8 of 15
what role do coenzymes play in respiration and photosynthesis?
they carry hydrogen atoms from one molecule to another.
9 of 15
NAD ...
is important throughout respiration
10 of 15
FAD...
is important in the krebs cycle
11 of 15
NADP...
is important in photosynthesis
12 of 15
what is the importance of the krebs cycle?
1) breaks down macromolecules 2) produces H atoms which are carried by NAD to etc for oxidative phosphorylation.this leads to the production of ATP. 3)4 carbon molecule is regenerated 4) it is a source of intermediates used to make fatty acids etc
13 of 15
anaerobic respiration in plants and some microorganisms...
pyruvate + reduced NAD ---> ethanol + CO2 + NAD
14 of 15
anaerobic respiration in animals...
pyruvate + reduced NAD ---> lactate + NAD
