Question

Carbohydrates are biological molecules made of carbon, hydrogen, and oxygen. There are different types of carbohydrate molecules, each with unique functions in living things.
4) Select the true statements.
Some carbohydrates are used to store excess glucose in plant and animal cells.
Carbohydrates are the primary energy source for the human body.
Humans consume carbohydrates through foods like bread, pasta, and bananas.
Disaccharides are large molecules made of hundreds of repeating units.

Answer 1

True:
- Some carbohydrates are used to store excess glucose in plant and animal cells. (e.g., starch in plants, glycogen in animals.)
- Carbohydrates are the primary energy source for the human body. (Glucose is the main fuel for cells, especially the brain and red blood cells.)
- Humans consume carbohydrates through foods like bread, pasta, and bananas.

False:
- Disaccharides are large molecules made of hundreds of repeating units. (Disaccharides are made of two monosaccharide units; polymers with hundreds of units are polysaccharides.)
