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
Premium Oxygen Cellular respiration Adenosine triphosphate
Organisms through cellular respiration convert energy into ATP. They do this in three distinct stages; glycolysis‚the Krebs cycle and the electron transport chain. The Krebs cycle and electron transport chain are both aerobic process and require oxygen. In certain conditions where oxygen is not present or is low some organisms switch from cellular respiration into alcoholic or lactic acid fermentation. Fermentation is an anaerobic‚ metabolic pathway used to oxidize nicotinamide adenine

AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas

To begin the analysis‚ the properties of the air at the base of the tower were examined. The wet and dry bulb temperatures of the air at the inlet were used to find the humidity‚ humid volume‚ and enthalpy of dry air. For example‚ in the first trial the dry bulb temperature was 22.5⁰C and the wet bulb was 16.5⁰C‚ and the properties found from the psychrometric chart are listed below. H_bottom=0.0095 kg/(kg dry air) V_bottom=0.85 m^3/(kg dry air) h_bottom=47 kg/(kg dry air) Then‚ the cross-sectional

Vital Signs Unit 1: Temperature‚ Pulse‚ and Respiration UNIT RATIONALE Important indicators of your patient’s/client’s health status are known as vital signs. Vital signs give you information about breathing‚ body temperature‚ and the heart. They are a good indication of how well the body systems are functioning. As a health care worker‚ you need to observe patients whenever you are near them. Your knowledge of vital signs and how to measure them helps you know when to report that a patient is having

The graph shows that the respiration rate does increase as the yeast concentration rises‚ but levels off and eventually reached its saturation point‚ or decline‚ which occurs at 8.5g. This decline may occur because there are too many yeast molecules in comparison to the glucose‚ which may lead to yeast cells hindering a collision thus lessening the reaction. The respiration rate increases as more yeast is added because it gives more opportunities for molecular collisions and so the amount of successful

Introduction The purpose of this experiment is to determine the effect that temperature has on the growth and respiration of yeast fermentation. The growth and respiration of the yeast can be determined by using a glucose/ yeast solution mixed with water in flasks set at different temperatures. Yeast in order to produce‚ has to make energy‚ to carry out all cellular functions (Spicer‚ & Holbrook‚ 2007). The concept that aerobic metabolism of all yeasts‚ is determined by the relative sizes of the transport

Lab 5Cellular Respiration Introduction: Cellular respiration is an ATP-producing catabolic process in which the ultimate electron acceptor is an inorganic molecule‚ such as oxygen. It is the release of energy from organic compounds by metabolic chemical oxidation in the mitochondria within each cell. Carbohydrates‚ proteins‚ and fats can all be metabolized as fuel‚ but cellular respiration is most often described as the oxidation of glucose‚ as follows: C6H12O6 + 6O2 → 6CO2 + 6H2O + 686 kilocalories

AP Biology I Investigation 6 AP Bio: Lab 6 Cellular Respiration Introduction Some knowledge that is needed before performing this lab are as follows: First of all‚ cellular respiration is the metabolic processes whereby certain organisms obtain energy from organic molecules. This process includes glycolysis‚ the Krebs cycle‚ and the Electron Transport Chain. Glycolysis is a process that takes place in te cytosol and it oxidizes glucose into two pyruvate. Glycolysis also makes ATP and NADH. The
