What proteins are involved in muscle contraction?

  1. Insulin and glucagon

  2. Hemoglobin and myoglobin

  3. Actin and myosin

  4. Estrogen and testosterone

The correct answer is: Actin and myosin

Actin and myosin are the two proteins involved in muscle contraction. Insulin and glucagon are hormones involved in regulating blood sugar levels, not muscle contraction. Hemoglobin and myoglobin are proteins involved in oxygen transport, but not in muscle contraction. Estrogen and testosterone are hormones involved in sexual development and functioning, not muscle contraction. Therefore, the correct answer is C.
