Which one of the following pairs of chemical substances is correctly ...
Explanation:The correct categorization among the given options is:C: Troponin and myosin - Complex proteins in striated musclesTroponin is a complex of three regulatory proteins (troponin C, troponin I, and troponin T) that is integral to muscle contraction in skeletal and cardiac muscle. - It functions in the regulation of muscle contraction by binding to calcium ions and initiating the movement of tropomyosin, which exposes the myosin-binding sites on actin filaments.• Myosin is a type of motor protein and a key component of the thick filaments in muscle cells. - It is involved in the process of muscle contraction by interacting with actin filaments, resulting in a sliding motion that shortens the muscle fibers and generates force.The other options are incorrect because:A: Calcitonin and thymosin - Thyroid hormones - Calcitonin is a hormone produced by the thyroid gland, but thymosin is not a thyroid hormone; it is a hormone produced by the thymus gland.B: Pepsin and prolactin - Two digestive enzymes secreted in stomach - Pepsin is a digestive enzyme secreted in the stomach, while prolactin is a hormone produced by the pituitary gland, not an enzyme or stomach secretion.D: Secretin and rhodopsin - Polypeptide hormones - Secretin is a polypeptide hormone produced by the small intestine, but rhodopsin is not a hormone; it is a light-sensitive protein found in the rod cells of the retina in the eye.
