Creatine Supplementation Creatine Phosphate
1,341 wordsCreatine is not an Herb, mineral, vitamin, hormone, or a steroid. It is also not those bread cubes that you scatter over your salad, either. Creatine is a natural nutrient found in our bodies and the bodies of most animals. Approximately ninety five percent is scattered throughout the rest of the body, with the highest concentrations in the heart, brain and testes. The human body gets most of the creatine it needs from the food or dietary supplements. Creatine is easily absorbed from the intesti...

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...

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...

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...

952 wordsGlycolysis Reaction 1 Glucose -> Glucose 6 -phosphate (G- 6 -P) The first stage of glycolysis starts from reaction of phosphorylation. Phosphorylation is catalyzed by hexokinase. It is an endothermic ATP dependent reaction and requires energy from ATP. ATP is hydrolyzed to ADP and phosphate. In such a way, glucose receives phosphate and energy. To sum up, the reaction is as follows: glucose + ATP a glucose- 6 -phosphate + ADP Reaction 2: Glucose 6 -phosphate (G- 6 -P) -> F- 6 -P (Fructose 6 -pho...

Neurodegenerative Diseases Muscle Cells
634 wordsMitochondria are the powerhouse of the cell. Their sole responsibility is to provide energy for the cell. They do this by synthesizing a molecule known as ATP, which the cell uses as energy. Mitochondria are different from the rest of the cell organelles because they contain their own DNA outside the nucleus. Mutations in this DNA have been found to be linked to Alzheimer s and other neurodegenerative diseases. Mutations in the DNA cause the mitochondria to function in other ways than it usually...
