QuestionAnswer
Define ATP(Adenosine Triphosphate) A substance present in all living cells that provides energy for many metabolic processes and is involved in making RNA.
What is glucose?The primary sugar in the blood and is the major source of energy for the body's cells
Define photosynthesisThe process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar
Define light dependant reactionsA photochemical reaction taking place in the thylakoid membranes of chloroplasts, where light energy is transformed into adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate (NADPH)
Define light independent reactionsA series of biochemical reactions in photosynthesis not requiring light to proceed, and ultimately produce organic molecules from carbon dioxide.
Define glycolysisThe breakdown of glucose by enzymes, releasing energy and pyruvic acid.
Define fermentationA metabolic process that produces chemical changes in organic substrates through the action of enzymes.
Define the electron transport chainA cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons that create adenosine triphosphate
Define Krebs cycleA sequence of reactions in which oxidation of acetic acid provides energy for storage in phosphate bonds
