Carbohydrates and Lipids

Front

What are carbohydrates?

Back

Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1. They serve as a primary energy source for living organisms.

Front

What are the three main types of carbohydrates?

Back

The three main types of carbohydrates are monosaccharides (simple sugars), disaccharides (two monosaccharides bonded together), and polysaccharides (long chains of monosaccharides).

Front

Define monosaccharides.

Back

Monosaccharides are the simplest form of carbohydrates, consisting of single sugar molecules like glucose and fructose.

Front

What is a disaccharide?

Back

A disaccharide is a carbohydrate formed by the bonding of two monosaccharides, such as sucrose (glucose + fructose) or lactose (glucose + galactose).

Front

What are polysaccharides?

Back

Polysaccharides are complex carbohydrates made up of long chains of monosaccharides, such as starch, glycogen, and cellulose.

Front

What is the role of cellulose in plants?

Back

Cellulose provides structural support to plant cell walls, helping maintain their shape and integrity.

Front

What are lipids?

Back

Lipids are a diverse group of hydrophobic organic molecules, including fats, oils, waxes, and steroids, that are important for energy storage and cellular structure.

Front

What is the function of phospholipids in cells?

Back

Phospholipids form the basic structure of cell membranes, creating a barrier that regulates the movement of substances in and out of the cell.

Front

What is the primary function of waxes in organisms?

Back

Waxes provide waterproof barriers that protect cells and organisms from water loss and environmental damage.

Front

What are fatty acids?

Back

Fatty acids are long hydrocarbon chains that are key components of lipids, particularly triglycerides and phospholipids.
