Key Concepts

Catabolic Reactions

Catabolic reactions involve the breakdown of complex molecules into smaller units, releasing energy that the cell can capture for various functions. These processes are integral to energy production and nutrient release, as they dismantle large biomolecules into simpler molecules and often result in the release of energy stored in chemical bonds.

Anabolic Reactions

Anabolic reactions are those metabolic pathways that construct larger molecules from smaller subunits, typically requiring an input of energy. These reactions are essential for processes like biosynthesis, growth, and repair where the organism builds complex molecules such as lipids, proteins, and nucleic acids from simpler compounds.

Transcript

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

00:04 A catabolic reaction is when you break down a big molecule to smaller molecules.

00:13 This is catabolic.

00:15 And what is anabolic? well, exactly the opposite.

00:18 When you build bigger molecules from smaller molecules.

00:22 Okay, this is anabolic reaction.

00:25 So with this, let's see at the options.

00:27 For example, options a says synthesis of lipids from glycerol and phary acids.

00:32 Glycerol and fatty acids are very basic fats, okay, and when you place them together, you're going to produce lipids, big lipids.

00:44 Okay, so you're particularly putting together smaller molecules to produce big molecules, and this is an example of anabolic reaction.

00:53 Okay, let's see option b.

00:55 It says glucose adds p, pi to form glucose 6 phosphate.

01:00 So you're practically putting together glucose plus pi and you're going to produce glucose 6 phosphate.

01:08 This occurs in glycolysis.

01:10 Okay.

01:10 And you're putting together two smaller molecules to produce a bigger molecule.

01:17 So it is an example of also anabolic reaction...
