In the glucose molecule, the chemical bonds between the. carbon (C) and hydrogen (H) atoms hold energy from the sun. 1. When our. bodies extract energy from food and convert it to a form that our cells can. use, we lose more than half of the total food energy as heat.
These secretions flow to the surface of the body or to the lining of a hollow structure in the body. The exocrine secretions are involved in many important functions, such as sweating, digestion and lubricating the eyes.There are many types of exocrine glands in the exocrine system.xamples include the salivary glands, liver, stomach, prostate, lacrimal glands, pancreas, sweat glands, sebaceous glands, and mammary glands. A few examples of conditions that afflict the exocrine system include infection, ulcer, cancer, tumors, obstruction, genetic conditions and sebaceous cysts.
cellular respiration of fat. Fats are first broken down into fatty acids, a process called beta-oxidation then converts the fatty acid tails into acetyl groups that can be combined with coenzyme A to form acetyl-CoA, which feeds into the Krebs cycle.cetyl-CoA. is an important molecule in metabolism, used in many biochemical reactions. Its main function is to convey the carbon atoms within the acetyl group to the citric acid cycle (Krebs cycle) to be oxidized for energy production.
