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

Which of the following statements concerning cellular metabolism is FALSE? Answer Energy obtained from nutrients or light is stored in the bonds of ATP. ATP is used in the formation of macromolecules. Enzymes are used in both catabolic and anabolic reactions. Macromolecules are

how starch and cellulose are treated to allow them to be used by the yeast? One potential ethanol feedstock is starch. Starch molecules are made up of long chains of glucose molecules. Thus‚ starchy materials can also be fermented after breaking starch molecules into simple glucose molecules. Examples of starchy materials commonly used around the world for ethanol production include cereal grains‚ potato‚ sweet potato‚ and cassava. A great amount of ethanol fuel is currently produced by starch

specific substrate acted on by Aldolase B is fructose-1-phosphate (F1P). This then is converted into DHAP and glyceraldehyde. Once the conversion is finished the product can enter the glycolysis cycle to from ATP or energy used for the body. “In normal cellular conditions‚ the primary enzymatic activity of aldolase B is to cleave fructose diphosphate (FDP).” (Roth‚ 2012) A5. Role of Aldolase B Aldolase B is the substance needed to breakdown fructose. Its specific role is to speed up the

enzyme but are temporarily bound for the duration of the reaction and then move away once it is completed. One example of this is NAD‚ which transfers hydrogen away from one molecule to become reduced NADH+. This occurs in both aerobic and anaerobic respiration in animals‚ whilst also in the light dependant and light independent reactions in plants. Temperature effects enzyme activity. Increasing the heat gives molecules more kinetic energy so they move around faster. This means

Definition/comparison questions Evolution / Selection Evolution is a slow continuous process of change that happens in plants and animals over a long period of time resulting in a change from simpler to more complex forms. This is the reason modern day plants and animals are different from those of past. The competition for resources will favour organisms with better adaptability and certain variations over others hence leading to change in the rate of occurrence of certain traits within that population

The effect of nutrition on the activity of Artemia franciscana Intro: In most ecosystems‚ the availability of nutrition is the most limiting factor of population growth and activity (Fábregas‚ 1997). If there is a lack of food resources in a community or a lack of certain specific dietary requirements‚ then the physiology of that community and it’s fecundity should be noticeably affected. Nutrients like carbohydrates‚ proteins and fats are carried around the body‚ along with oxygen from the

Comment on the statement below: ‘Glycolysis and Gluconeogenesis are reciprocally regulated’ Reciprocally regulated means when one process takes place in a cell‚ the other process will essentially inactivated. This regulation ensures that either glycolysis or gluconeogenesis predominate as to prevent concurrent activity in two closely parallel pathways‚ where if both Glycolysis and Gluconeogenesis
