Explanation The electron microscopic investigations, when performed on secretory cells of adrenal spongiocyte and pancreatic islets, certain ultrastructural features are found. A pancreatic islet is a small group of cells that generates hormones for regulating the blood glucose level. The pancreatic islet cells are secreted directly into the bloodstream by five types of cells. The alpha cells secrete glucagon, while beta cells produce insulin and amylin. The delta cells produce the hormone somatostatin. The pancreas shows two different types of parenchymal tissue that include exocrine acini ducts and endocrine islets of Langerhans...

One of the ways for a cell to generate ATP is through the oxidative phosphorylation. In oxidative phosphorylation 3 ATP are produced from every one NADH molecule. In respiration, every glucose molecule produces 10 NADH molecules. If a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?
