Chapter 7 and 8 discuss and give in depth details on photosynthesis and cellular respiration. They are the exact opposites in what they set out to complete in the cells of a leaf. Photosynthesis takes light energy and separates it in the chloroplasts to create glucose. Cellular respiration breaks down glucose to provide energy for the cell. The similarities between them include overlap in some of the enzymes and products and reactants utilized. The differences include the cycles and steps taken to

Bacterial Energetics and Membranes Abstract The Mg2+/Ca2+ ATP synthase present in all bacterial membranes‚ particularly E. coli‚ couples ATP synthesis to the proton (H+) gradient produced by the ETC‚ a process known as oxidative phosphorylation. The gradient acts to power the ATPase‚ so that it may phosphorylate ADP to produce ATP. The reverse reaction of this process‚ or hydrolysis of ATP into ADP and Pi‚ may be used to observe ATPase activity when the resulting Pi is quantitatively measured

Analysis: In this lab we measured the rate of respiration of germinating mung beans and germinating peas at room temperature and 10 degrees Celsius. The rates of respiration at room temperature were higher than the rates of respiration in cold water. The reaction rate of the germinating peas at room temperature was .0125 ml/min and the reaction rate of the peas at 10 degrees Celsius was .0095 ml/min. The same is true for the germinating mung beans. At room temperature the rate of reaction was .0105

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

phosphorylating ADP. Many prokaryotes and virtually all Eukaryotes phosphorylate ADP either through fermentation (anaerobic) or respiration (aerobic). Both of these processes involve oxidation of foodstuffs‚ yet only the latter requires oxygen. Cellular respiration is a very complex process that consists of many steps that take place inside the cell‚ in an organelle called a mitochondrion. Mitochondria are responsible for converting digested nutrients into the energy-yielding molecule adenosine

Photosynthesis and Cellular Respiration Nina R. McCray May 5‚ 2015 Biology Lab (SCIE207-1502-A-07) LaDonna McCowan-Ferrier Photosynthesis and Cellular Respiration Lab Report Introduction This is an investigation of the effect of the intensity of light (photosynthesis) have on the rate of cellular respiration (measured as the number of oxygen bubbles). We will determine whether or not it is possible to examine the relationship between photosynthesis and cellular respiration under controlled

Energetics 5.1 5.1.1 Endothermic: A reaction in which energy is absorbed. If your reactants are at a lower energy level than your products then the reaction is endothermic this means it has a + ΔH° Exothermic: A reaction in which energy is released. If your reactants are at a higher energy level than your products then the reaction is exothermic this means it has a ΔH° Standard Enthalpy ( ΔH°) The internal energy stored in the reactants. Only changes in enthalpy can be measured

Testing for Cellular Respiration by Balloon Inflation Experiment Number 2 Abstract: Through a timed test it was discovered which substance A or substance B contained glucose and when combined with yeast results in respiration; it was found that substance A contained glucose and resulted in respiration when combined with yeast. At 0 minutes all four balloon’s circumference was 9 centimeters; substance B and salt remained the same circumference‚ 9 centimeters‚ for
