WebRelationship between structure & function. The structure of mitochondria makes them well adapted to their function; They have a large surface area due to the presence of cristae (inner folds) which enables the membrane to hold many electron transport chain proteins and ATP synthase enzymes; More active cell types can have larger mitochondria with … WebPhotosynthesis occurs in two stages: the light-dependent stage, which takes place in the thylakoids, and the light-independent stage, which takes place in the stroma. During the light-dependent stage of photosynthesis: Reduced NADP is produced when hydrogen ions combine with the carrier molecule NADP using electrons from the photolysis of water.
WebExam Tip Remember – the oxygen produced during the photolysis of water is a waste product of this process. The hydrogen ions and electrons produced during the photolysis of water are useful products. The electrons replace those that have been lost from the primary pigment molecule (chlorophyll). WebPlace a test tube containing 0.5 cm 3 chloroplast extract into a test tube rack set up at a set distance from a lamp A beaker of water can be placed in between the lamp and the rack here to prevent a temperature increase due to heat from the lamp Add 5 cm 3 DCPIP solution to the chloroplast extract and mix together using a clean glass rod
