Abstract The experiment aims to observe if simpler substrates makes the rate of cellular respiration faster. Using yeast‚ smith fermentation tubes and different substrates namely‚ starch‚ lactose‚ sucrose‚ glucose and fructose‚ which are from different kinds of carbohydrates‚ ranging from the simplest sugars glucose and fructose to the polysaccharide starch and water as the control‚ the hypothesis was tested. With the span of thirty minutes with five-minute intervals‚ the height of carbon dioxide

LIGHT IN PHOTOSYNTHESIS Theory: Leaf discs float normally. When the air spaces are infiltrated with the solution the overall density of the leaf disc increases and the disc sinks. The infiltration solution includes a small amount of sodium bicarbonate. The bicarbonate ions serve as the carbon source for photosynthesis. As photosynthesis proceeds oxygen is released into the interior of the leaf which changes the buoyancy – causing the discs to rise. Since cellular respiration is taking place

disaccharides are sugars. They all have the basic formula (CH2O)n and can be classified according to how many carbon atoms they contain. 3C = triose sugars e.g. glyceraldehyde C3H5O2 5C = pentose sugars e.g. ribose C5H10O5 6C = hexose sugars e.g. glucose C6H12O6 Formation of disaccharides - typical exam questions Common exam questions include: 1. Name the reaction involved when a disaccharide is formed 2. Name the type of bond formed 3. Show‚ by drawing a diagram‚ how a disaccharide is formed Questions

The process captures energy from sunlight and converts that energy to ATP and NADH which it uses to reduce CO2 into simple sugars. The process follows the equation: 6CO2+H2O+Light C6H12O6+6CO2. CO2 is converted into simple sugars in the Calvin cycle‚ which occurs in three stages. It takes 6 “turns” of the Calvin cycle for the organism to produce one molecule of glucose. Organisms that are autotrophs use photosynthesis to make their
