are three main stages of cellular respiration are glycolysis‚ the citric acid cycle‚ and electron transport/oxidative phosphorylation. Enzymes play a role in cellular respiration. Enzymes are proteins that catalyze or affect the rate of chemical reactions. The main purpose of enzymes in cellular respiration is to help in transporting electrons from one molecule to another. These transfers are called redox reactions. Where the loss of electrons from one molecule oxidation must correspond with more

Jolly Nguyen 11C Conditions needed for effective enzyme action Aim: To investigate the activity of enzymes and how might the activity be effected in different conditions. Hypothesis: Temperature rises and change of substrate concentration may cause denaturation of the protein of enzymes. So as the temperature rises the amount of active enzyme progressively decreases‚ and the rate is slowed. Exposure to heat causes atoms to vibrate violently and this disrupts bonds within globular proteins

Rate of Reaction of Enzyme Amylase Research Question: How will changing the percentage of sodium chloride concentration affect the rate of reaction of enzyme amylase‚ measured using the absorbance of starch and iodine with a spectrophotometer. Introduction: Amylase is an enzyme that is involved in the human digestive process. Found in both the human pancreas and the human saliva‚ amylase breaks down starch into sugar so that large molecules can be easily digested1. Like all enzymes‚ amylase

What are amylases? Amylases are enzymes that break down starch or glycogen. Amylases are produced by a variety of living organisms‚ ranging from bacteria to plants and humans. Bacteria and fungi secrete amylases to the outside of their cells to carry out extracellular digestion. When they have broken down the insoluble starch‚ the soluble end products such as (glucose or maltose) are absorbed into their cells. Amylases are classified based on how they break down starch molecules i. α-amylase

Enzyme assay lab report Health and safety: 4-nitrophenol is harmful. Introduction: Enzymes are quaternary structured proteins that are specific biological catalysts that speed up a reaction without being used up. They contain an active site that allows substrate to bind to a specific area on the enzyme which is of a complimentary shape of the substrate. There are two models of enzyme action‚ the Lock and Key model and the Induced Fit model. The Lock and Key model states that the enzyme has a specific

Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution‚ slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide‚ a powerful and potentially

Investigating the Effect of Concentration on the Rate of Enzyme Catalysed Reaction To investigate the effect of concentration on the rate of enzyme catalysed reaction I must know all the factors that affect it in order to investigate in this. Here are all the factors: Temperature- Enzyme like it warm but not too hot. Enzymes are biological catalysts‚ which speed up chemical reactions. They work most efficiently at the optimum point (37°C). If they are below 37°C they will work
