Photosynthesis & cellular respiration are the main pathways of energy flow in living things. Photosynthesis is a process by which plants and some other organisms convert‚ light energy from the sun‚ CO2 from the air & H2O from the earth‚ into chemical energy stored in molecules like glucose. Cellular respiration is a process in which O2 is delivered to cells in an organism & metabolic process in cells leads to the production of ATP by the breakdown of organic substances. Cellular respiration occurs in the

Carbon cycle essay I eat some corn during lunch and then cellular respiration takes place. During the process of cellular respiration the glucose and oxygen I took in will be turned into carbon‚ water‚ and ATP. I will expel this carbon through my lungs. This carbon then is used by photosynthesis of phytoplankton in the water. During the photosynthesis that takes place‚ sunlight‚ water‚ and carbon are taken in by the plankton and then a fish eats this phytoplankton and this organism dies. When the

Chapter 6 Measuring 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

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
Premium Cellular respiration Oxygen Carbon dioxide
Oxygen – Carbon dioxide Cycle The Carbon Dioxide- Oxygen Cycle relates to the relationship between Carbon Dioxide [CO2] breathing plants and Oxygen [O2] breathing life forms. All oxygen-breathing life forms take in Oxygen and exhale CO2. Plants take in the CO2 and use it in their photosynthesis process and in turn give off oxygen. The Carbon Dioxide-Oxygen Cycle is a continuously occurring process whereby animals inhale Oxygen and then exhale carbon dioxide‚ and plants use the CO2 and "exhale"

similar for cellular respiration and photosynthesis are almost exact opposites. Photosynthesis is anabolic; it builds up glucose‚ or sugar‚ from light energy‚ water and carbon dioxide. The chemical equation for photosynthesis is: 6CO2 + 6H2O + Light Energy C6H12O6 + 6O2. Cellular respiration‚ on the other hand‚ is catabolic. It breaks down glucose to form carbon dioxide and water. The chemical equation for cellular respiration is: C6H12O6 + 6O2 6CO2 + 6H2O + 38 ATP. Cellular respiration and photosynthesis

Glycolysis‚ the breakdown of glucose‚ occurs in the cytosol. This reaction does not require oxygen‚ while all the following reactions after this do. Two ATP molecules are invested in the beginning. Two molecules of glyceraldehyde 3-phosphate (GAP) are produced with the reduction of NAD+ to NADH. By the end of this reaction‚ two pyruvates (two 3C

carbohydrates goes through a process called glycolysis. Glycolysis a series of biochemical reactions in which one glucose molecule is oxidized into two pyruvic acid molecules and a small amount of adenosine triphosphate (ATP). Generation of high energy molecules are used as cellular energy sources in aerobic and anaerobic respiration. The products formed through glycolysis usually enter into the citric acid cycle and the electron transport chain to produce more energy. Fructose enters the glycolytic pathway

DEVELOPMENT OF THE INTERNODE LENGTH OF VIGNA RADIATA WHEN GROWN UNDER DIFFERENT LIGHT INTENSITIES ABSTRACT Throughout their growth plants exhibit varying ways to adapt and change depending on their circumstances‚ with changes in the amount of available light being a major factor in plant growth. The aim of the study was to determine whether there are significant differences in the growth patterns of Vigna radiata when grown under varying light intensities. Plants were grown in two different light
