AQA JUNE 2022 BIOLOGY AS LEVEL 7401 PAPER 1aerobic respiration>>> an exothermic reaction in which glucose is broken down using oxygen to produce carbon dioxide and water and release energy for the cellsanaerobic respiration>>> an exothermic reaction in which glucose is broken down in the absence of oxygen to produce lactic acid in animals and ethanol and carbon dioxide in plants and yeast. A small amount of energy is transferred for the cellsexothermic reaction>>> a reaction that transfers energy to the environmentglycogen>>> carbohydrate store in animalslactic acid>>> the end product of anaerobic respiration in animal cellsoxygen debt>>> the extra oxygen that must be taken into the body after exercise has stopped to complete the aerobic respiration of lactic acidMitochondria>>> Organelle that is the site of respirationResponses to exercise>>> Heart rate increases, Breathing rate increases, glycogen in muscles is converted to glucoseendothermic reaction>>> a reaction that requires a transfer of energy from the environmentglucose>>> a simple sugarlimiting factors>>> limit the rate of a reaction, for example photosynthesisphotosynthesis>>> the process by which plants make food using carbon dioxide, water, and lightReactants for photosynthesis>>> water and carbon dioxideProducts of photosynthesis>>> glucose and oxygenChloroplast>>> Site of photosynthesiswhite blood cells>>> Blood
