Essay On Chloroplast

2208 Words 9 Pages
Chloroplast are found in plants, they are responsible for the metabolism of energy to produce food for plants by breaking down Carbon dioxide, water and sunlight through a process called Photosynthesis. Once Carbon Dioxide enters a plant through stomata pores in a plant, water is absorbed through the roots of a plant and sunlight captured by chlorophyll pigments inside the chloroplast which is actually inside the thylakoids. It 's the russian doll complex., it is within the chloroplast that we begin the production of food for the plant. Within the chloroplast exist these tiny oval thin disk called thylakoids filled with lumen. Thylakoids are responsible for “catching” and storing light which then will be metabolized into food. The thylakoids …show more content…
Glycolysis results in 2 pyruvates and 2 NADH , which are rich in energy and are used later to power ATP. Typically Oxygen is needed for cellular respiration but in glycolysis it is not necessary which makes it an Anaerobic process. In the absence of Oxygen, the pyruvates created through Glycolysis are rerouted through Fermentation. In the absence of Oxygen in order to keep Glycolysis going it will need NAD+, so fermentation frees up an NADH. The Krebs Cycle and the Electron Transport Chain are both aerobic processes that require oxygen.Unlike glycolysis, the Krebs cycle does not take place in the cytoplasm instead it occurs within the inner membrane of the mitochondria. The Krebs Cycle uses the Glycolysis byproducts, pyruvates, to create 2 ATPS per glucose molecule plus some energy. First one of the pyruvate is oxidized by combining with an oxygen. Remember pyruvates are rich in carbon! Now that 2 pyruvates are left, it creates COA, acetyl coenzyme A, which create another 2 molecules of NADH. Each pyruvate creates 3 NADH and 1 FADH per cycle and since pyruvates come from glucose and glucose through the process of glycolysis creates 2 pyruvates, then 6 NADH and 2 FADH are …show more content…
Diffusion is the result of random movement from particles in liquids and gasses. The random movement has no directional net movement but the particles do move along in straight line. Their movement is considered thermal motions because it is driven by energy that is absorbed from their surroundings. That is why solids like ice are frozen, their particles are still and not attempting to spread out.When discussing diffusion, think about how perfume or room deodorizers like fabreeze manage to spread out, the evaporation of the liquid into the air demonstrates how diffusion works going from the higher concentration of where the scent was sprayed until the particles begin to move and bounce off across the room spreading out and into the lower concentration area. In the case for Osmosis, is the diffusion of water through the membrane into the opposite site where the concentrations of the solution has higher solute concentrations and where a solute diffuses through a permeable membrane that is only permeable to those solvents. The diffusion and ends when the concentration on either side of the membrane are equalized.This process is driven by osmotic pressure, where solvents in a higher concentration want to go to the opposite side of the membrane where the concentrations are lower. Paramecia organisms need to constantly pump out
