90. Which of the following statements is correct regarding reversible inhibition of enzymes? ① The catalytic efficiency of enzyme is  in the presence of competitive inhibitors. ② Competitive inhibitors are substrate analogs or transtion state analogs. ③ Uncompetitive inhibitors combine only with enzyme-substrate complex. ④ In the presence of inhibitors, the initial rate of enzyme-catalyzed reactions is positively correlated with substrate concentration. ⑤ The binding of noncompetitive inhibitors to enzymes is inhibited by substrate. (A) ①②③ (B) ②③④ (C) ③④⑤ (D) ①③④ (E) ②④⑤

23. Which of the following statements BEST integrates the structural and physiological function of human skin as an organ? (A) The epidermis is a vascularized epithelial layer composed primarily of fibroblasts that provide tensile strength and thermal insulation. (B) Melanocytes located in the dermis synthesize keratin, which forms the main waterproof barrier of the skin. (C) The hypodermis is derived from ectoderm and is responsible for forming the stratified squamous epithelium of the skin. (D) Adipocytes in the epidermis secrete collagen fibers that anchor the skin to underlying muscle tissue. NTHU115 (E) The dermis contains connective tissue, blood vessels, sensory receptors, and glands, enabling skin to function in protection, sensation, and thermoregulation.

24. During skeletal muscle contraction, which of the following statements BEST supports the sliding filament theory? (A) The length of the thick (myosin) filaments shortens as ATP is hydrolyzed, resulting in a decreased A band length. (B) The thin (actin) filaments are depolymerizing during contraction, allowing for sarcomere shortening. (C) An increase in the width of the I band due to reduced overlap between actin and myosin filaments. (D) The distance between Z-dises decreases while the A band remains constant in length. (E) The H zone becomes larger as myosin heads detach during contraction.
