Proteína

Proteins, linked by peptide bonds, are crucial for numerous body functions, including acting as hormones, enzymes, and immunological signals. They also form structures like hair. DNA sequences encode these proteins, which are integral to all cells in the body.

What type of bonds link proteins in long chains?

• Covalent bonds

• Peptide bonds

• Hydrogen bonds

• Ionic bonds

Which of the following is NOT a function of proteins?

• Acting as hormones

• Serving as enzymes

• Providing genetic information

• Forming hair

Proteins that act as enzymes are crucial for what?

• Providing structural support

• Storing energy

• Speeding up chemical reactions

• Transporting oxygen

How do proteins function in the immune system?

• By transporting nutrients

• By forming antibodies

• By providing structural support

• By storing energy

What encodes the proteins that are part of all cells?

• DNA sequences

• Carbohydrate chains

• RNA sequences

• Lipid molecules
