___________ stimulates the interstitial cells of the testes to secrete_____________
Luteinizing hormone (LH); testosterone
Follicle-stimulating hormone (FSH); androgen-binding protein (ABP)
Luteinizing hormone (LH); androgen-binding protein (ABP)
Luteinizing hormone (LH); estrogen
The Correct Answer is A
A. Luteinizing hormone (LH); testosterone: Luteinizing hormone (LH) stimulates the interstitial cells (Leydig cells) of the testes to produce and secrete testosterone.
B. Follicle-stimulating hormone (FSH); androgen-binding protein (ABP): Follicle-stimulating hormone (FSH) stimulates the Sertoli cells to produce androgen-binding protein (ABP), but it does not stimulate the interstitial cells to secrete testosterone.
C. Luteinizing hormone (LH); androgen-binding protein (ABP): Luteinizing hormone (LH) stimulates the secretion of testosterone, not androgen-binding protein (ABP). ABP is stimulated by FSH.
D. Luteinizing hormone (LH); estrogen: Luteinizing hormone (LH) stimulates the secretion of testosterone, not estrogen. Estrogen is primarily produced in females and also in males in smaller amounts.

C. Pyruvate is the end product of glycolysis, where glucose is broken down into two molecules of pyruvate.
D. Acetyl-CoA is formed from pyruvate during the transition step before the Krebs cycle, not directly from glycolysis.
Correct Answer is True
Explanation
Segmentation is a type of intestinal contraction that mixes chyme with digestive enzymes and increases its contact with the mucosa, facilitating digestion and absorption. Propulsion is primarily accomplished by peristalsis, not segmentation. This statement is accurate in describing segmentation's role in the small intestine.
