Cellular respiration is the process of breaking down chemical energy‚ most commonly glucose and oxygen‚ for use in the body as ATP with the release of water and carbon dioxide as bi-products (Mauseth‚ 2014). This process can be observed by careful analysis of the metabolic rate which is the total amount of energy released by an organism per unit mass. The respiratory quotient (R.Q) is the ratio of CO2 molecules lost per O2 molecules consumed which can be used to determine the efficiency of the metabolic

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

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 cellular respiration? In Photosynthesis light energy along with carbon dioxide are used to make molecules or (food energy). In Cellular Respiration food energy is broken down to form ATP. 3. Why is photosynthesis important to you? Photosynthesis is important because plants‚ bacteria‚ and small animals use photosynthesis

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

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
