Describe the role of the citric acid cycle as a central metabolic mechanism. Explain what happens to the cells’ abilities to oxidize acetyl CoA when intermediates of the cycle are drained off for amino acid biosynthesis. Describe the three steps in photosynthesis‚ detailing the interrelationships among them. (c.f. the discussion in the online classroom). For this assignment you don’t need to use other sources besides the information given in the commentary‚ animations‚ and/or textbook. However‚ you may

Anabolism and Catabolism Anabolism and catabolism are two phases of the human body’s metabolic process. Metabolism is a process that is essential for humans to live a healthy and productive life. The anabolism phase is the process where the body builds up the needed molecules. This phase requires energy in order to complete the process. Catabolism releases energy that can be used by the organism. This phase is the process of breaking down the complex molecules into smaller portions. These two

Enzymes‚ ATP‚ Hereditary Fructose Intolerance WGU Role of enzymes in processes The role of an enzyme is to catalyze a chemical reaction. Usually an enzyme increases the rate of speed of a reaction. Enzymes break down molecules in our body faster than they would normally break down without enzymes. Enzymes work at specific temperatures and pH levels. (Wolfe‚ 2000). For example‚ a stomach enzyme works better in a more acidic environment‚ whereas intestinal enzymes work

Case 1: Hereditary fructose intolerance Enzymes are proteins that increase the rate of chemical activity. Their three dimensional structure determines their function‚ and is made of chains of amino acids that have folded into a specific shape with a unique property. Enzymes lower the activation energy needed for a chemical reaction‚ therefore speeding up the process. Multiple enzymes work together in metabolic pathways‚ taking a product (end result) of one metabolic reaction as a substrate (substance
