Protein Power

Muscle tissue movement

Structural support for connective tissue

Catalysis in the glycolytic pathway

Transport of oxygen in the blood (correct)

Positively charged

Aromatic

Nonpolar, aliphatic (correct)

Polar, uncharged

Peptides are non-polar and hydrophobic, while proteins are polar and hydrophilic

Peptides are typically smaller than proteins, containing 2 to 50 amino acids, while proteins are larger, containing more than 50 amino acids (correct)

Peptides contain only one amino acid, while proteins contain multiple amino acids

Peptides are involved in muscle tissue movement, while proteins are involved in structural support for connective tissue
