Explanation / Answer
1. What is the major function of luteinizing hormone in males?
(B) promoting spermatogenesis
Luteinizing hormone promotes the production of spermatogenesis.
2. Which of the following hormones reduce appetite?
(b) leptin
Leptin is commonly considered to be anorexigenic act as appetite suppressant.
3. Which metabolic pathways would be utilised for endurance activities
(a) glycolysis
4. Which cells secrete hydrogen ions into the lumen of the stomach?
(b) parietal
Hydrogen ions are secreted separately from the cytoplasm of parietal cells and mixed in the canaliculi.Parietal cells are also known as oxyntic or delomorphous cells.
5.which part of the nephron has a primary function of reabsorption of ions ,nutrients/organic molecules and water?
(b) proximal convoluted tubule.
