What is glycolosis in a nutshell
series of 10 catalyzed reactions
where does glycolosis take place
in cytoplasm
does glycolosis require o2
no cuz of anaerobic but can function with o2 aerobic.
What happens to the glucose molecule?
its a 6-c molecule that splits into 3-c pyruvates
overall chemical reaction for glycolosis is
glucose + 2 ADP + 2 P i + 2 NAD + → 2 pyruvate + 2 ATP + 2 NADH + 2H +
how much free energy is captured from one mol of glucose
only 2% of free energy is captured from one mol of glucose.
what is the earliest form of energy?
metabolism
Describe steps of Glycolytic pathway
1) ATP is used to add a phosphate onto Glucose turning it into Glucose - 6 phosphate, 2) then this turns into Fructose - 6 Phosphate, 3) another atp is used to add another phosphate turning Fructose -6 phosphate into Fructose - 6 bisphosphate 4) Splitting occurs and the 6 - C molecule turns into 3 -C molecules 5) Pgal occurs and the loss of electrons occurs ( how many?) 6)oxidation occurs, each 3-c molecule loses electrons and NAD + turns into NADH 7)enough energy is released to add P to ADP which resuults into ATP production 8) second phosphate is released creating another ATP and forming pyruvate. in total for both pathways 4 ATP Created 2 ATP used 2 NADH made 2 Pyruvate
