Lab 4: Endocrine System Physiology | 1. | | Refer to Activity 1: Determining Baseline Metabolic Rates. How did the baseline metabolic rates of the three rats differ? Answer: | The metabolic rates for the thyroidectomized and hypophysectomized rats were lower than that of the normal rat. | | | 2. | | Why did the metabolic rates differ? Check all that apply: Answers: | The hypophysectomized rat lacked thyroid-stimulating hormone. The thyroidectomized rat lacked thyroxine hormone.

Introduction Enzymes are key players in metabolism. A metabolism is the organic processes in a cell or an organism that are necessary for life. An enzyme affects the rate at which a reaction occurs when the activation energy is lowered. In this reaction the reactant is called the substrate which is that combine with enzymes molecules to form a temporary enzyme substrate complex. During this products are formed and the enzyme molecules released is unchanged. For the substrate complex to form the

Enzymes Introduction This study allows the investigation of enzymatic reactions behavior. An enzyme is a protein catalyst reaction by lowering the activation energy required for that reaction. The enzyme is unaltered at the completion of the reaction. In this stimulation the amount of product produced during the course of an enzymatic product produced during the course of an enzymatic reaction will be measured. Hypothesis 1: What is the estimate optimal of ph? Hypothesis 2: What is the estimate optimal of temperature

Effects of Temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity INTRODUCTION Enzymes‚ proteins that act as catalysts‚ are the most important type of protein[1]. Catalysts speed up chemical reactions and can go without being used up or changed [3] Without enzymes‚ the biochemical reactions that take place will react too slowly to keep up with the metabolic needs and the life functions of organisms. Catecholase is a reaction between oxygen and catechol

Enzymes and ATP Enzymes act as protein catalysts in biochemical processes Enzymes bind to a substrate and forms the enzyme substrate complex. Enzymes work by lowering the energy of activation. Activation energy must be supplied for the reaction to begin‚ once supplied‚ the reaction can proceed on its own. Enzymes can speed up events. They are not used by during the reaction because the enzyme stays the same‚ it does not change during the reaction. (Hudon-Miller‚ Enzymes‚ 2013) Enzymes act as
