Question

function\ttype of protein
regulate gene expression and organize dna
catalyze biochemical reactions by lowering activation energy
transport molecules across cell membranes or within the body
facilitate communication between cells as receptors or hormones
enable movement within cells or of the organism
protect against pathogens by neutralizing foreign invaders
antibodies\tchannel proteins, peripheral proteins, and hemoglobin
insulin\tactin and myosin
amylases, lipases, proteases, and nucleases\ttranscription factors and histones

Explanation:

1. Transcription factors and histones regulate gene expression and organize DNA.
2. Enzymes like amylases, lipases, proteases, and nucleases catalyze biochemical reactions by lowering activation energy.
3. Channel proteins, peripheral proteins, and hemoglobin transport molecules across cell membranes or within the body.
4. Insulin (a hormone) and some receptor - like proteins facilitate communication between cells.
5. Actin and myosin enable movement within cells or of the organism.
6. Antibodies protect against pathogens by neutralizing foreign invaders.

Answer:

1. Transcription factors and histones
2. Amylases, lipases, proteases, and nucleases
