Question

Carbohydrates check all that apply
1) are polysaccharides
2) store energy
3) Are made from carbs hydrogens and oxygens
4) Are synthesized through peptide bonding

Answer 1

To evaluate the statements about carbohydrates, let's analyze each one:

1) **Are polysaccharides** - This is partially true, as carbohydrates can be monosaccharides (simple sugars), disaccharides (two sugars), or polysaccharides (many sugars). So while some carbohydrates are polysaccharides, not all are.

2) **Store energy** - True. Carbohydrates, particularly polysaccharides like starch and glycogen, serve as energy storage molecules in organisms.

3) **Are made from carbon, hydrogens, and oxygens** - True. Carbohydrates are organic compounds made primarily of carbon, hydrogen, and oxygen, typically in a ratio of approximately 1:2:1.

4) **Are synthesized through peptide bonding** - False. Carbohydrates are synthesized through glycosidic bonds, not peptide bonds. Peptide bonds are used to link amino acids in proteins.

Based on the evaluations:

- **True statements**: 2, 3
- **Partially true**: 1 (but not applicable for all carbohydrates)
- **False statement**: 4

So, the correct responses are 2 and 3.
