Metabolism is the sum of chemical processes that occur in the body.
00:04
And we have two types, catabolic and anabolic.
00:08
So we have four options here.
00:10
First, catabolic builds molecules, anabolic breaks them down.
00:17
B, catabolic breaks down all molecules, anabolic breaks down organic ones.
00:25
C, catabolic breaks down organic molecules for energy.
00:29
Anabolic builds them.
00:30
Or d, catabolic breaks them down, anabolic builds them.
00:38
So what's the answer here? well, first of all, catabolic and anabolic are kind of opposites.
00:44
So catabolic means to break down, anabolic means to build up.
00:48
So in a reaction, one molecule is more complex, it's larger, and the others are simpler.
00:58
So, for example, if you look at the process of photosynthesis and respiration, on one end you have co2.
01:09
On one end you have co2 and you have, on the other you have oxygen and you have glucose.
01:22
This is a reversible reaction...
