All of these are true about glycolysis except a, it occurs in the cytoplasm.
00:06
B, it uses and produces atp.
00:09
C, it produces atp by oxidative phosphorylation.
00:14
D, it involves the conversion of a molecule of glucose into two molecules of pyruvate.
00:20
E, it is common to both respiration and fermentation.
00:24
So it should be true.
00:25
First of all, it does happen in the cytoplasm.
00:28
And d is also true.
00:30
So glycolysis takes in glucose and spits out two molecules of piruvate.
00:39
It also spits out a net profit of 2 atp and an nadh.
00:46
When i say net profit of 280p, that's because to start glycolysis off, you do need atp.
00:53
So for the first couple of steps of glycolysis, you are phosphorylating the glucose.
01:00
You add a phosphate group and then you have to add another when you've got the fructose phosphate to get fructose -16 bisphosphate.
01:09
So to get to fructose -1 -6 bisphosphate, you require 2 atp.
01:19
And then later in glycolysis at the end you get 4 atp out and that's why you only get a profit of 2.
01:26
Which means b is a true statement.
01:28
It uses and produces atp.
01:30
Then finally e is true as well.
01:34
So if oxygen is available, this pyruvate is going to be decarboxylated...
