photosynthesis‚ but also cellular respiration (Reddy et al. 1970). Cellular respiration‚ an array of metabolic processes‚ in plants is the oxidation of the chemical energy from acquired nutrients into energy in the form of ATP or adenosine triphosphate. In a germinating pea‚ which respires‚ the mitochondria provides cellular ATP‚ this is possible because it is utilizing stored nutrients (Stupnikova et al. 2006) In order to determine if a non-germinating pea respires‚ its respiration rates can be quantified

Analyzing the Rate of Cellular Respiration in Germinating and Non-germinating Black-eyed Peas I. Hypothesis If the cellular respiration rate of germinating black-eyed peas and non-germinating black-eyed peas is compared then the germinating black-eyed peas will have the higher respiration rate. II. Background Organisms need some sort of energy to facilitate their growth and development. Usually‚ this energy is in the form of adenosine triphosphate‚ or ATP. Cellular respiration is the process that synthesizes

152-35 Professor Weller 14 February 2012 Effects of Temperature on Goldfish Respiration Introduction This experiment was designed to identify the effect of cold-water temperatures on the respiration rate of goldfish. The respiration rates helped to identify the goldfish as being ectotherms or endotherms. Organisms exchange gases with their environment through a process called respiration or breathing. Aerobic respiration‚ also known as aerobic metabolism‚ occurs when oxygen is taken into the body

Section 33 Yeast Cell Respiration 10/04/2010 Part B: Explanation of Results All cells carry out the process of cell respiration in order to meet their energy needs. It is advantageous for cells to have the ability to metabolize different substrates. In this experiment‚ we investigated each sugar’s (glucose‚ lactose‚ sucrose‚ fructose‚ and lactose/lactaid) cell respiration rate. When referring to my group’s graph and data‚ glucose ended up with the highest respiration rate (1‚177.2 ppm/min)

Compare and Contrast Photosynthesis and Cellular Respiration Opposites in photosynthesis and cellular respiration. Is that photosynthesis is taking in carbon dioxide and water by absorbing energy from the sun and then release oxygen and storing glucose. In cellular respiration glucose and oxygen enters and they are converted into carbon dioxide‚ water and ATP energy. But they work alike because they both have electron transport chains and similarly ATP.

The purpose of this lab was to investigate how size of seeds impact respiration rate. It was hypothesized that bigger seed will require more oxygen because more energy is needed to sustain the seed’s homeostasis. For this experiment 4 groups was set up with 0.5 mL worth of the following seeds: peas (1) ‚ black beans (1)‚ radish seeds‚ and glass beads (control). The black bean served as the biggest size‚ peas were medium‚ and radish seeds were the smallest. After setting up the microrespirometer and

Cellular respiration is a metabolic process that all living organisms use to harvest from foods in the form of adenosine triphosphate. There are three stages of cellular respiration-glycolysis‚ citric acid cycle‚ and electron transport chain. What is the role of glycolysis? Include the reactants and the products. Where

Lil Dejay C4 2/10/14 Photosynthesis: Making Energy Chloroplasts Photosynthesis is a process in which sunlight energy is used to make glucose. The site of photosynthesis is in the chloroplast – an organelle found in the leaves of green plants. The main functions of chloroplasts are to produce food (glucose) during photosynthesis‚ and to store food energy. Chloroplasts contain the pigment‚ chlorophyll. Chlorophyll absorbs most of the colors in the color spectrum‚ and reflects only green and yellow

foods that we eat. Metabolism is a chemical activity which uses cellular respiration. (Wright‚ 2007) Aerobic respiration is respiration with oxygen present. (Wright‚ 2007) The formula for cellular respiration is below: Glucose +oxygen = Energy‚ carbon dioxide and water. Carbon dioxide and water are the waste products from creating energy. Respiration can happen without oxygen. This process is called anaerobic respiration. The equation glucose+ oxygen which produces energy along with the bi-products
