Photosynthesis And Cellular Respiration Lab Report
Chapter 7 and 8 discuss and give in depth details on photosynthesis and cellular respiration. They are the exact opposites in what they set out to complete in the cells of a leaf. Photosynthesis takes light energy and separates it in the chloroplasts to create glucose. Cellular respiration breaks down glucose to provide energy for the cell. The similarities between them include overlap in some of the enzymes and products and reactants utilized. The differences include the cycles and steps taken to produce the final products.
To begin with the similarities which include the utilization of enzymes and parts of used and produced.. In photosynthesis oxalacetate, malate, pyruvate, 1,3-bisphosphoglycerate, and G3P or glyceraldehyde-3-phosphate …show more content…
For photosynthesis there are two distinct parts which include those of the light reactions and those of the dark. In the light reaction the main focus is pigments and the two photosystems. Photosystem II functions first and only fires if it absorbs a wavelength of 680 nm. Then photosystem I functions but only is 700 nm wavelengths have been absorbed. This process takes place in the thylakoid of the chloroplast. Once fired the calvin cycle starts, which is the dark reaction. The calvin cycle has three steps the first of which being carbon fixation, that is catalyzed by the enzyme rubisco. The second being reduction and the third being regeneration of the carbon dioxide acceptor or the creation of ribulose bisphosphate. This dark reaction takes place in the stroma of the chloroplast. Whereas in cellular respiration there four main parts. The first part being glycolysis which includes four steps, this breaks down glucose into pyruvate. Second we have the oxidation of pyruvate, this changes the pyruvate into acetyl-CoA then the kreb’s cycle starts. Kreb’s cycle has three segments and nine reactions producing three NADH, one FADH2, ATP, and carbon dioxide. The last part of cellular respiration includes the electron transport chain and chemiosmosis the name for the movement of electrons through a gradient making
