This lab was split up into two different experiments‚ using different variables in each. During the first section of the lab‚ we investigated the what the effect of light is on both photosynthesis and cellular respiration. Our hypothesis about this effect was that the cuvette representing ‘no light’‚ being covered in foil‚ would result in a yellow CO2 indicator fluid‚ meaning that there was a decrease in pH and a high level of CO2 was present. Additionally‚ we hypothesized that the cuvette that was

Cellular Respiration Project Objective Answers 1. The overall equation for Cellular Respiration is 6O2 + C6H12O6 6H2O + 6CO2 + energy. Overall‚ it is the reverse reaction of photosynthesis‚ but chemically‚ the steps involved are very different. All you have to do is just flip both sides of the equation of photosynthesis‚ and you have the opposite‚ which is the equation for cellular respiration. They are reversible chemical reactions‚ meaning that the products of one process are the exact

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

Respiration of Sugars by Yeast 1. PROBLEM STATEMENT: What is the effect of the type of sugar on the amount of carbon dioxide released by Yeast during aerobic respiration? 2. HYPOTHESIS: If the type of sugar is changed‚ the amount of carbon dioxide created will then increase because sugar is needed to for respiration so occur. If Fructose is added to the Yeast it will then respire the most Co2 because fructose is the largest sugar‚ its like using a hundred dollar bill instead of single dollars

Photosynthesis and cellular respiration Introduction: Photosynthesis is the process which used by plants to capture light energy and use it to do chemical reactions that change carbon dioxide and water into oxygen and energy (ATP)‚ carbohydrates just like sugar. Cellular respiration is the process that releases energy by breaking down glucose and other food with oxygen. Plants cells do photosynthesis and cellular respiration both ‚but animal cells can only do the cellular respiration. In photosynthesis reaction

Cellular Respiration Photosynthesis Organelles Mitochondria Chloroplast Organelle Structures The double-membraned mitochondrion can be loosely described as a large wrinkled bag packed inside of a smaller‚ unwrinkled bag. The two membranes create distinct compartments within the organelle‚ and are themselves very different in structure and in function. Two membranes contain and protect the inner parts of the chloroplast. The stroma is an area inside of the chloroplast where reactions occur and starches

BIO 101 Lecture Notes for Respiration‚ Fermentation‚ and Photosynthesis Respiration During aerobic respiration‚ glucose is completely oxidized (all H’s removed) leaving CO2 as an endproduct. The H’s are taken by coenzymes (NAD and FAD) to the electron transport chain. There the energy is drained from the hydrogen electrons and the energy is used to make ATP. The H’s are ultimately accepted by O2 to make H2O as an endproduct. Respiration occurs in three major stages: 1) Glycolysis

energy production. They are also the responsible location for which respiration takes place. Mitochondria contain enzymes that help convert food material into adenosine triphosphate (ATP)‚ which can be used directly by the cell as an energy source. Mitochondria tend to be concentrated near cellular structures that require large inputs of energy‚ such as the flagellum. The role of the mitochondria is very important in respiration. In the presence of oxygen‚ pyruvate or fatty acids‚ can be further

ANATOMY AND PHYSIOLOGY AN INTRODUCTION TO RESPIRATION In this essay we will consider a few major aspects of respiration. We shall first consider the interesting history of the study of respiration before moving on to our modern understanding of respiration. We will look at the structure and function of the respiratory system including the upper and lower respiratory tracts with a note on the control system. Secondly we will consider the physiology of respiration. Thirdly we will discuss some of the major

Lab 8 - Chemical and Physical Processes of Digestion (p.105) Introduction: In this lab‚ I will study how digestion of carbohydrates‚ proteins‚ and fats occurs. I will define Key Terms that describe what will occur in the experiments; I will conduct an experiment for each Activity and provide all resulting Data as well as answer Questions from each Activity. I will then provide a short Summary for what I learned in each Activity. Key Terms: Enzymes (p. 105) – Speed up chemical
