I) Introduction In this lab‚ a test was conducted to determine how the relative redox activity of chloroplasts from spinach leaves‚ which were performing photosynthesis‚ would change when in the presence or absence of light. To observe these changes in redox activity‚ the chloroplasts were exposed to DCPIP‚ a chemical that changes color according to such activity. By determining the redox activity of the chloroplasts‚ it could then be inferred which chloroplasts were photosynthesizing more actively

respiration. The main role is to transport electrons formed from NADH to oxygen in order to release the energy cells use to make ATP. Photosynthesis: What is the overall goal of photosynthesis? The overall goal of photosynthesis is to convert light energy from the sun into a chemical energy of sugar and other organic molecules. For example‚ apple trees use photosynthesis to produce both oxygen and fruit. Animal life needs oxygen

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.

Associate Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? A living version of internal combustion-is the main way that chemical energy is harvested from food and converted to ATP energy‚ it is also called an aerobic process‚ which is just another way of saying that it requires oxygen. So cellular respiration is defined as the aerobic harvesting of chemical energy

Chemoheterotrophic organisms obtain energy from the oxidation of organic compounds 7. What is photosynthesis and where does it take place? Photosynthesis is a process used by plants and other autotrophic organisms to convert light energy‚ normally from the sun‚ into chemical energy that can be used to fuel the organisms’ activities. Carbohydrates‚ such as sugars‚ are synthesized from carbon dioxide and water Photosynthesis is the means by which plants harvest light energy to make their own food it takes place

cycles to feed. I explained to him how plants use photosynthesis and respiration to produce sugars for food then releasing the used energy into our atmosphere. Four main factors needed to produce these processes are sunlight‚ oxygen‚ carbon dioxide‚ and water. I would explain to Van Helmont that under a microscope plants have cells that have tiny green pigments that contain chloroplast where all of the chemical reactions are computed. In photosynthesis a plant takes in carbon dioxide‚ water‚ and sunlight
