Respiration and Photosynthesis by Wo Sau Man https://padlet.com/wsman/9i1yfhqcr2ad 1. NAD, FAD and NADP are involved in the transfer of hydrogen in cells. Describe, in detail, the role of these molecules within a palisade mesophyll cell. (7 + 3 marks) 2. Both photosynthesis and aerobic respiration are important processes for energy transformation. Contrast the processes of energy transformation in photosynthesis and aerobic respiration.

In photosynthesis, water will be broken down into hydrogen and oxygen by photolysis. NADP is the hydrogen acceptor to accept the hydrogen from photolysis of water to form NADPH
 
 2. Photosynthesis starts with absorbing light energy by chlorophyll molecules. However, respiration starts with the breakdown of glucose into pyruvate by energy from ATP by glycolysis.]]> 2020-03-19 12:44:30 UTC https://padlet.com/wsman/9i1yfhqcr2ad/wish/466190610 5B 10 Chau Leong Kwan, r201622001 https://padlet.com/wsman/9i1yfhqcr2ad/wish/466194777 1. In aerobic respiration, NAD+ is reduced to NADH in glycolysis and Kerbs cycle; FAD is reduced to FADH in the Kerbs cycle . In which NADH and FADH is oxidized to maintain the electron transport chain and the H+ proton could activate the ATP synthase.   
2 .The aim for photosynthesis is to produce organic substance 6-C glucose by light energy while the aerobic respiration is aim to break down the 6-C glucose into inorganic substance CO2 + H2O. In which photosynthesis has a net uptake of energy while aerobic respiration has a net release of energy.]]> 2020-03-19 12:47:34 UTC https://padlet.com/wsman/9i1yfhqcr2ad/wish/466194777 5A13 Matthew Kwan r201512036 https://padlet.com/wsman/9i1yfhqcr2ad/wish/469632012 1,In anaerobic respiration, NADH reduces the pyruvate formed by glycolysis, ethanol, carbon dioxideand ATP. NAD is regenerates during alcoholic fermintation, Nad reduced to form NADH during glycolysis and NAD accepted the hyrogen and NADH is then oxidised to form NAD during pyruvate reduced to ethanol.

2,Photosynthesis energy conversion is fromn light energy to chemical energy in food, while in aerobic respiration is fromn chemical energy in food, to chemical energy in ATP and heat energy.]]> 2020-03-22 13:29:07 UTC https://padlet.com/wsman/9i1yfhqcr2ad/wish/469632012 5B05 Angel Yu On Ki r201512120 https://padlet.com/wsman/9i1yfhqcr2ad/wish/469671741 1. NADP will use in photosynthesis. It helps to do the photolysis of water. NAD and FAD will use in aerobic respiration. NAD is used in glycolysis and Krebs cycle to form NADH by taking one hydrogen atom. FAD is used in Krebs cycle, it will absorb hydrogen atom and become FADH.

2. Photosynthesis produce carbohydrates and oxygen. While aerobic respiration produce carbon dioxide and water in the end products.]]> 2020-03-22 14:16:03 UTC https://padlet.com/wsman/9i1yfhqcr2ad/wish/469671741 5B13 Marco https://padlet.com/wsman/9i1yfhqcr2ad/wish/470949230 1. NADP is a hydrogen carrier in photosynthesis, while NAD and FAD are hydrogen carriers in respiration. NADP is reduced to NADPH through photolysis of water, while NAD and FAD are reduced to NADH and FADH respectively in Krebs cycle

2. In photosynthesis, the high energy intermediates are high energy electrons emitted from activated chlorophyll; while those in aerobic respiration are ATP, NADH and FADH from glycolysis and Krebs cycle
