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.

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.
