What is metabolism? All living things must have an unceasing supply of energy and matter. The transformation of this energy and matter within the body is called metabolism. Metabolism includes two different types: catabolism and anabolism. Catabolism is destructive metabolism. Typically‚ in catabolism‚ larger organic molecules are broken down into smaller constituents. This usually occurs with the release of energy. Anabolism is constructive metabolism. Typically‚ in anabolism‚ small precursor

Effects of Activators and Ethanol on Fermentation Rates In this lab we examined how the rate of fermentation is influenced by the type of substrate‚ and activators and inhibitors. We used four fermentation tubes in which we separately combined yeast with MgSO4‚ pyruvate‚ ethanol‚ and glucose. At five minute intervals we recorded the volume of gas produced in each fermentation tube. Our results are displayed in the graph. Our results supported the prediction that pyruvate is an activator of

from their diagnosis. Symptoms are also similar to that of vaginal yeast infections and trichomoniasis. A combination of multiple bacteria must be present together for the problem to develop. Bacterial vaginosis typically features a reduction in the number of the normal hydrogen peroxide-producing lactobacilli in the vagina. All together‚ there is an increase in concentration of other types of bacteria‚ especially anaerobic bacteria (bacteria that grow in the absence of oxygen). As a result

Final Biology Exam Review Unit One: Cellular Processes Definitions: Apoptosis – Known as cell suicide‚ lysosomes break open and decompose the entire cell. Triglyceride – A lipid molecule composed of glycerol and three fatty acids. Simple diffusion – Movement of particles from an area of high concentration to an area of low concentration. It goes through the phospholipid bilayer. Facilitated diffusion – Diffusion of particles through the cell membrane‚ assisted by transmembrane proteins

A net of two ATPs are produced as the process uses two ATPs and produces four. Glycolysis consists of ten chemical reactions; each reaction is catalysed using a different enzyme. Oxygen is not required during glycolysis so it is considered anaerobic respiration. Glycolysis must be regulated so that energy is produce only when required. During glycolysis there are three enzymes that catalyse or inhibit the rate of reaction. These are hexokinase‚ phosphofructokinase and pyruvate kinase. During the
