The process that does not release energy from glucose is photosynthesis; instead, it produces glucose. Processes that release energy from glucose include fermentation and respiration. Photosynthesis is a process by which plants and organisms convert the sun’s energy into glucose and oxygen.
The process begins when proteins contained in organelles found in plants called chloroplasts absorb energy from sunlight. They store the energy as chemical energy with the molecules adenosine triphosphate and nicotinamide adenine dinucleotide phosphate. These two types of molecules carry energy generated by the light reactions in photosynthesis and help produce glucose and oxygen gas during a process known as carbon fixation.
