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.
Does photosynthesis release energy?
In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
Does photosynthesis release energy from glucose?
Most life on Earth depends on photosynthesis. The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O 2 ) and chemical energy stored in glucose (a sugar).
What releases the energy in glucose?
What is released when a sugar molecule is broken down? In cells use oxygen to release energy stored in sugars such as glucose. In fact, most of the energy used by the cells in your body is provided by cellular respiration .
Does glucose release energy from glucose?
Glucose and other food molecules are broken down by controlled stepwise oxidation to provide chemical energy in the form of ATP and NADH.
Does photosynthesis release oxygen?
During photosynthesis, plants take in carbon dioxide (CO 2 ) and water (H 2 O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
What type of energy is movement?
Kinetic energy is the motion of waves, electrons, atoms, molecules, substances, and objects.
Where is energy stored in glucose?
Energy is stored in the chemical bonds of the glucose molecules .
Which process does not release energy from glucose?
Explanation: The process of photosynthesis is not associated with the release of energy from the glucose molecule. This process is performed by the plant system to form chemical energy by using light energy which can later be stored in carbohydrate molecules.
How is glucose converted to ATP?
Cells convert glucose to ATP in a process called cellular respiration . Cellular respiration: process of turning glucose into energy In the form of ATP. Before cellular respiration can begin, glucose must be refined into a form that is usable by the mitochondrion.
Where does the glucose from respiration come from?
It comes from the glucose in foods that you eat ! Energy is stored in the chemical bonds of the glucose molecules. Once glucose is digested and transported to your cells, a process called cellular respiration releases the stored energy and converts it to energy that your cells can use.
Is glucose a carbohydrate?
These carbohydrates are composed of sugars (such as fructose and glucose) which have simple chemical structures composed of only one sugar (monosaccharides) or two sugars (disaccharides).
Can glucose be broken down without oxygen?
Without oxygen, organisms can split glucose into just two molecules of pyruvate . This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules.
Does photosynthesis produce ATP?
The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP.
Is it true or false carbon dioxide is released during photosynthesis?
The reaction of photosynthesis involves carbon dioxide and water and forms carbohydrate and oxygen in the presence of sunlight. Animals take oxygen from plants and release carbon dioxide into the environment. From the above information we have found that carbon dioxide is not released during photosynthesis .
How oxygen is produced in photosynthesis?
During photosynthesis, plants take in carbon dioxide (CO 2 ) and water (H 2 O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
