Lab #2: Energy in Cell Virtual Lab - Week 3 NAME: ________________________________________ 1. What is the importance of the light and dark reactions in photosynthesis? Photosynthesis works by absorbing light. Our sun gives off energy and the chlorophyll from the plant absorb this energy. The energy is then used to separate water into hydrogen and oxygen and then they combine hydrogen and carbon dioxide to make sugars. 2. What happens to food energy during photosynthesis? During

Biochemistry GRT1 Task 4: Metabolism Enzyme Induced Fit Model and Activation Energy Role of Enzymes: Enzymes are proteins that act as catalysts during a biochemical process. Catalysts are non-changing enzymes that can increase or decrease activation energy to accelerate or slow down a biochemical reaction without using additional energy. Enzymes break down molecules in our body faster than they would normally break down without enzymes. On the biochemical level‚ enzymes work at precise

Yeast Fermentation Lab Report SBI4U Chaweewan. Sirakawin Present to Ms.Allinotte November 21. 2014 Introduction: Fermentation is a metabolic pathway that produce ATP molecules under anaerobic conditions (only undergoes glycolysis)‚ NAD+ is used directly in glycolysis to form ATP molecules‚ which is not as efficient as cellular respiration because only 2ATP molecules are formed during the glycolysis. One type of fermentation is alcohol fermentation‚ it produces

CHAPTER 8 AN INTRODUCTION TO METABOLISM Metabolism‚ Energy‚ and Life 1. Explain the role of catabolic and anabolic pathways in cellular metabolism. Catabolic means the molecule is broken down into smaller parts. Anabolic means molecules are used to build bigger compounds. 2. Distinguish between kinetic and potential energy. Kinetic energy is the energy of object in motion. Potential energy is the energy a object has due to its position or traits. 3. Distinguish between

Please provide an example of Homeostasis and Negative Feedback in our environment. Be sure not to duplicate a classmates’ answer. 2. Identify some genetically engineered products currently available. Homeostasis is a point of balance or internal equilibrium. All kinds of systems — both living and non-living — can work to keep themselves in this state of balance‚ but the word "homeostasis" is most often used in biology‚ particularly to describe how the human body reacts to changes and keeps
Free Metabolism Insulin Glucose
When glucose levels are high: insulin receptors --place glucose receptors on membrane to allow glucose - glucose into cell. In the bonds of glucose‚ energy is placed. but isn’t useable. need to destroy the glucose in controlled way. Organic compounds used. ATP is useable energy. Active transport uses ATP‚ changes shape of proteins‚ going against conc. gradient‚ changes form atp to adp +Pi as one phosphate group lost.

Action of enzymes as catalysts in biochemical processes * Enzymes acts as catalyst and increase the rate of all the chemical reactions. * Enzymes are also described by two properties like all other catalysts. It composed of two main functions. * The first function is that‚ they increase the rate of chemical reactions by without consumed themselves or undergo any change or alteration in the reaction. . ( Zemitec et‚al 2008). * The second function is‚ they increase reaction rates

Valer Enea Unit 2‚ Case Study 1 -- The Cellular Level of Organization GE258 Q: Assuming Joesph’s heart has stopped‚ what cellular processes and membrane functions are going to be affected by the loss of oxygen‚ blood glucose‚ and waste removal? A: Oxygen and blood glucose are essential ions that are necessary for the pumping of the heart. Their delivery to the heart will slow down. Carbon dioxide levels will increase -- this causes the Ph levels to drop. Mitochondria will no longer have

Joseph’s Story The Cellular lever is essential to the homeostasis of an entire organism. In this case study you will learn the impact that a Myocardial Infarction (Heart Attack) has on heart cells. The Patient (Joseph) is a 38 year old male who started back smoking after quitting for 3 years. He has been busy working long hours and the stress of his job was wearing on his body. Joseph was playing catch with his 12 year old Marcus when his heart stopped beating. Do to the loss of Oxygen‚ Blood
