What is the energy needed for photosynthesis and cellular respiration?
Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.
What is energy role in cellular respiration?
Summary. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
What is the role of energy in photosynthesis?
Photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen gas. The potential energy stored in the molecular bonds of glucose becomes kinetic energy after cellular respiration that cells can use to do work like move muscles and run metabolic processes.
What is the photosynthesis of energy requirement?
The minimum quantum requirement for photosynthesis under optimal conditions is about nine. Thus, the energy used is 9 × 50, or 450 kcal per mole of oxygen evolved. Third, rates of photosynthesis in bright sunlight sometimes exceed the needs of the plants, resulting in the formation of excess sugars and starch.
What energy is needed by photosynthetic organisms during photosynthesis?
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
Is energy released in cellular respiration?
Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.
What is the cellular respiration of energy requirement?
The energy required for cellular activities is provided directly by molecules of adenosine triphosphate (ATP). ATP is made of one adenosine molecule and three phosphate groups, called Pi for short. Each molecule of ATP stores a small quantity of chemical energy.
What is the energy needed for the photosynthesis process?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Is energy released during photosynthesis?
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food.
