Okay, i want to answer this question is talk about catabolism.
00:03
Remember that catabolism is the process by which you are going to break down a large molecule into smaller molecules.
00:13
For example, if you have glycogen, there is a polymer of glucose, a catabolism is going to be when you break this glycogen down to many glucose molecules.
00:25
Imagine glycogen like this, and each of these circles are glucose molecules.
00:29
So this is glycogen.
00:30
If you break this glycogen down into many different subpoenas of molecules of glucose, this is catabolism.
00:36
Okay, specifically in this case, this is called glycogenolysis.
00:39
So this question says, which is the following metabolic pathway is catabolic? option is this is glucogenesis or glycogenesis.
00:48
And this is not the answer because glycogenesis is this process by which you produce glycogen from many glucose molecules.
00:53
So this is anabolism.
00:55
This is not catabolism.
00:56
Option b says glycogenolysis.
00:58
And this is true.
00:59
And this is the answer for this question.
01:00
Because glycogenolysis is by which is a process by which you are going to break glycogen down into many glucose molecules.
01:08
So you're breaking down a large, a large molecule into many smaller molecules.
01:12
So option b is true.
01:14
Option c is glucognogenesis and this is false because gluconogenesis is the process by which you're going to produce in glucose from non -carbohydrate sources and this is also an abolition.
01:24
Option this is lipogenesis and this is also false because lipogenesis is the process by which you're going to produce lipids from smaller molecules that are glycerol and fatty acids.
01:32
So you're producing a larger molecule from a smaller molecule.
01:35
So that's an abhorlesin.
01:38
That is practically the opposite to catabolism...
