Electron Transport Hydrogen Ions
778 wordsElectron transport is the last phase and most important phase of cell respiration. It accounts for most of the ATP made in cell respiration. Cell respiration makes a total of thirty eight Atp's, two from Glycolysis, two from the Krebs cycle and thirty four from electron transports. Electron transport takes place after Glycolysis and the Krebs cycle. Glycolysis and the Krebs cycle make their ATP through substrate level Phosphorylation while electron transport makes its ATP through oxidative phosp...

Cell Membrane Electron Transport Chain Biochemical Pathway
684 words1. The cell membrane structure is vital to the life of the cell. The cell membrane is shaped as having a phosphate head at the very outer surface, and two fatty acid tails hanging from it. The membrane is double, so at the tip of the fatty acid tails, there are two more fatty acid tails attached to another phosphate head. This is what it looks like: The reason the cell membrane is shaped like this is mainly to control the water flow in and out of the cell. Water is very important to the cell: if...

2 H 2 O Creatine Phosphate
1,714 wordsWith the aid of diagrams provide a summary of how the following energy systems work. Energy systems; introduction Energy systems are cellular levels processes used to produce Adenosine Triphosphate (ATP) figure 1. This is an adenosine molecule linked to three high-energy phosphates that acts as an energy store for the cell. The energy is released when ATPase, an enzyme, reacts with ATP to produce ADP and Pi, e. g. ATP ADP + Pi There are three energy systems that do this; The Creatine Phosphate S...

Plasma Membrane Permeable Membrane
777 wordsThe plasma membrane is the boundary of life; this selectively permeable membrane allows the cell to maintain a unique internal environment and to control the movement of materials into and out of the cell. The phospholipid bilayer (fluid music model) with specific membrane proteins accounts for he selective permeability of the membrane and passive and active transport mechanisms. Membrane phospholipids are amphipathic. Cell membranes are phospholipid bilayers with the hydrophobic hydrocarbon tai...

Carbon Dioxide Hydrogen Ions
1,424 wordsPhotosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules. Photosynthesis powers almost all trophic chains and food webs on the Earth. The net process of photosynthesis is described by the following equation: 6 CO 2 + 6 H 2 O + Light Energy = C 6 H 12 O 6 + 6 O 2 This equation simply means that carbon dioxide from the air and water combine in the presence of sunli...

E T C Plasma Membrane
448 wordsThe way in which a membrane is assembled decides what is allowed in and out of a cell and how it advances through the cell membrane. Certain molecules can simply pass through the cell membrane through diffusion. Diffusion is a type of passive transport meaning no energy is used for the substance to enter or leave the cell. Another way for molecules to enter the cell is through facilitated diffusion. When a molecule is simply to large to diffuse through the cell membrane it can enter the cell thr...

Introduction Out of all the organelles there are two that have fascinated microbiologists for the past hundred years. The first is the mitochondria, nicknamed the powerhouse of the cell. The second is the chloroplast in plant cells that have functions similar to those of the mitochondria. What do these organelles do? What are the similar...
