Define metabolism. The totality of an organism?s chemical reactions, consisting of catabolic and anabolic pathways, which manage the material and energy resources of the organism. 2. There are two types of reactions in metabolic pathways: anabolic and catabolic. a. Which reactions release energy? catabolic b. Which reactions consume energy? anabolic c. Which reactions build up larger molecules? catabolic d. Which reactions break down molecules? catabolic

AP Biology Lab #2 Enzyme Catalysis Overview: In this lab you will observe the conversion of hydrogen peroxide (H2O2) to water and oxygen gas by the enzyme catalase, and then measure the amount of oxygen generated. You will also calculate the rate of an enzyme-catalyzed reaction. Objectives: Before doing this lab, please review the following from your text and/or notes: Structure, function of enzymes How temperature, pH, enzyme concentration and substrate concentration affect the initial reaction rates of enzyme-catalyzed reactions Review the terms: Catalyst Catalase Catalysis After doing the lab, you should be able to:

Potato Osmosis Biology SL - ATh INVESTIGATION ?Potato Osmosis? INTRODUCTION Osmosis is a process that occurs at a cellular level that entails the spontaneous net movement of water through a semi-permeable membrane from a region of low solute concentration to an area of high solute concentration in order to equalize the level of water in each region. Involved in this process are hypotonic, hypertonic and isotonic solutions. A hypotonic solution is one with a lower osmotic pressure, indicating that the net movement of water moves into the said solution whereas a hypertonic solution is one with a higher osmotic pressure, thus the net movement of water will be leaving the hypertonic solution. Lastly, an isotonic solution entails no net

Analyses Osmosis and Diffusion Osmosis and Diffusion are processes of passive transport. In this lab we studied the basic concepts of molecular movement in solutions. During the execution of the experiment, I became aware that molecules are in constant motion and tend to move from areas of higher concentration to those of lower concentration. Diffusion is the movement of molecules following that concentration gradient. It occurs on the diverse states of matter. Osmosis refers to the specialized diffusion of molecules of water through a selectively permeable membrane.

Campbell's Biology, 9e (Reece et al.) Chapter 8 An Introduction to Metabolism This chapter lays the foundations for the chapters on respiration and photosynthesis. Key concepts are as follows: The laws of thermodynamics govern energy transformations by living organisms, metabolic reactions couple energy-harvesting reactions to reactions that accomplish cellular work, and enzymes increase the rates of reaction. Understanding the properties of enzymes, how they work, and how their activities are regulated is necessary to achieve an understanding of metabolic pathways. Multiple-Choice Questions 1) Which term most precisely describes the cellular process of breaking down large molecules into smaller ones? A) catalysis B) metabolism C) anabolism D) dehydration E) catabolism
