glycolysis Flashcards
how many ATP molecules are used in the first phase of glycolysis?
2
How many ATP molecules (net gain) are produced in glycolysis?
2
go over lactic acid and fermentation
go over lactic acid and fermentation
also go over phosphorylation of glucose
Where is NADH given off in glycolysis?
between glyceraldehyde-3-phosphate and 1,3 biphosphoglycerate or first step in second phase
In animal and plant cells in ______conditions, pyruvate is metabolized by the TCA cycle and the electron transport/oxidative phosphorylation pathway to generate ATP energy.
aerobic
n contracting muscle in __________ conditions, pyruvate is converted into lactic acid
anaerobic
n yeast in ___________ conditions, pyruvate is converted into ethanol
anaerobic
In yeast under anaerobic conditions, the conversion of pyruvate into ethanol and
carbon dioxide serves to regenerate the important molecule __________.
NAD+
When exercise ceases and _______ becomes available, lactic acid can be directly converted back to pyruvate, which is used to fuel the
TCA cycle
oxygen
But if the anaerobic conditions continue, the excess lactic acid is transported in the blood to the liver and resynthesized into ________
glucose
Glucose is the only monosaccharide that can enter the glycolysis pathway
False
what three other Mono’s can enter the glycolysis cycle?
Galactose, fructose, and mannose
where does mannose enter the glycolysis pathway?
F6P
