AQA GCSE Biology Bioenergetics what are the products of photosynthesis ? oxygen and glucose how does water enter a plant ? roor hair cells Brainpower Read More What is an endothermic reaction? A reaction that takes in energy from the surroundings what are uses for glucose in plants ? - for respiration - to make starch - to make cellulose In the required practical to investigate how light intensity affects photosynthesis, what would you expect to happen as the distance betwe...

AQA Biology paper 1 Exam Questions With 100% Correct Answers aerobic respiration - answeran exothermic reaction in which glucose is broken down using oxygen to produce carbon dioxide and water and release energy for the cells anaerobic respiration - answeran 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.

AQA GCSE Biology - Paper 1 Rated A+ What does a nucleus do? ️It contains genetic material and controls the activities of the cell What does cytoplasm do? ️It's a gel-like substance where most of the chemical reactions happen. It contains enzymes that control these chemical reactions What does a cell membrane do? ️It holds the cell together and controls what goes in and out What do mitochondria do? ️These are where most of the reactions for aerobic respiration occur. Respirat...
