Which of these gives the most 80p per molecule of glucose oxidized? we've got alcoholic fermentation, lactic acid fermentation, anaerobic respiration, aerobic respiration, or they all give the same amount.
00:17
Okay, so let's start with these two types of respiration.
00:21
Anerobic is without oxygen, aerobic is with oxygen.
00:28
So what kinds of processes do we see? well, anaerobic, you get glycolysis, aerobic you get glycolysis, but then you also get the crept cycle and the electron transport chain.
00:43
So these are the two types of respiration that you see, and glycolysis has a net production of two atp molecules.
00:55
So you get two atp from there, you get two atp from there.
01:02
So anaerobic respiration cuts for process short, because you need oxygen to carry out these later two steps, and the electron transport chain is where you get most of the atp from the breakdown of glucose.
01:15
So between the two, you definitely get more from aerobic rather than anaerobic.
01:21
Because anaerobic you get two, aerobic, there's a hypothetical maximum of 36 to 38, but in reality, from aerobic, in practice, you tend to get about 30 to 32 molecules of atp, per glucose that enters this whole process.
01:40
So that sorts those two out, and we can roll out e as well.
01:44
What about a and b? what about fermentation? what fermentation is not respiration? fermentation does not produce atp...
