Key Concepts

Catabolism

Catabolic processes refer to metabolic pathways that involve breaking down large, complex molecules into smaller, simpler components. These reactions release energy, often in the form of ATP or heat, and include processes such as hydrolysis where major molecules are split into their building blocks.

Anabolism

Anabolic processes encompass metabolic pathways that build larger, more complex molecules from smaller, simpler ones, requiring an input of energy typically provided by ATP. These synthesis reactions are essential for cellular growth, repair, and maintenance.

Transcript

00:01 Okay, in order to solve this question, let's talk about catabolic and anabolic reactions.

00:05 A catabolic reaction is when you break down a big molecule into smaller molecules.

00:17 This is a catabolic reaction.

00:23 And what is an anabolic reaction? anabolic reaction is practically the opposite, okay? it is when you produce a bigger molecule from smaller molecules.

00:35 Okay, these are the definitions of anabolic reaction.

00:37 And catabolic reactions.

00:39 Let's see the options.

00:40 Option a says digestion of fats, of fats, thoracids, and glycerol.

00:50 This is an example of catabolic reaction.

00:56 Why? because fats are macromolecules, are big molecules.

01:00 And when you break down these fats, you are going to produce fripariacis and glycerol that are going to be useful to produce energy.

01:10 Okay, so this is a catalytic reaction because you are breaking down a bigger molecule to smaller molecules.

01:16 Option b, it says hydrolysis of proteins into amino acids.

01:20 Protein, this is going to be a protein.

01:23 Remember the protein is a polymer of amino acids.

01:26 It means if this is an amino acid, then when you put many amino acids together, you're going to produce a protein.
