select all that apply\nchoose all the statements that are true of proteins.\n□ they carry the instructions that control a cells activities.\n□ they act as receptors on cells surfaces.\n□ they make up one of the subunits, or building blocks, of triglycerides.\n□ they catalyze chemical reactions.\n□ they make up molecules that can transport oxygen.
Answer
Brief Explanations:
- DNA, not proteins, carries instructions that control a cell's activities.
- Proteins can act as receptors on cell surfaces for signal - recognition.
- Fatty acids and glycerol make up triglycerides, not proteins.
- Enzymes (a type of protein) can catalyze chemical reactions.
- Hemoglobin, a protein, can transport oxygen.
Answer:
They act as receptors on cells' surfaces. They catalyze chemical reactions. They make up molecules that can transport oxygen.
