What is collagen? Collagen is a simple protein made up of amino-acids. Amino acids are built from carbon‚ oxygen and hydrogen. In fact collagen makes up approximately 30% of the protein within the body. As a structure Collagen is intensely strong and is a vital protein that is found all over the body: In tendons and ligaments. It plays an important role in the protection function of the skin in that it helps limit the absorption and spreading of pathogenic substances‚ environmental toxins‚ micro

temperature have on the oxygen production of enzymes in an animal’s liver? A temperature which is too high would be able to produce little to no oxygen because of the extreme temperature. Just like a temperature too high‚ a temperature which is too low would also produce little to no oxygen for the same reason. Animals that have livers are considered warm-blooded‚ with very warm temperatures; therefore it would make sense for a warm temperature to produce the most oxygen; but one that is not too

D1 – Analyse how two body systems interrelate to perform named functions The circulatory system and the respiratory system work closely together to ensure that organ tissues and systems receive enough oxygen. Oxygen is required for cellular functions such as cell respiration. This is so the body’s organs and cells can work at fully; it is done by releasing chemical energy with in stored foods. The air breathed in and held in the lungs is transferred to the blood. The blood is circulated by

Experiment 1 Cyanobacteria Oxygen Production Through Photosynthesis Date Performed: September 2‚ 2014 I. Introduction a. Background Cyanobacteria or blue green algae are renowned for their tolerability and susceptibility even in wide range of environmental conditions‚ a characteristic of many primitive organisms. CNB are believed to be the agents of autotrophic origin of life thus they probably represent the survivors of the earliest photosynthetic plants‚ along with photosynthetic and chemosynthetic

this substance together would release a certain amount of oxygen‚ this varied over the course of six minutes. We tested the yeast a total of four times using the gas sensor each time. The gas sensor would be left in the bottle for at least six minutes. The oxygen

d) In the lungs and tissue e) i) Deoxygenated blood has less oxygen than the alveolar air. ii) This causes oxygen to diffuse out of the alveolus into the blood capillaries. f) Oxygen molecules pass through and dissolve in the thin film of moisture in the alveolar wall. The oxygen then pass through the thin layer of alveolar epithelial cells and the endothelial cells of capillary wall. g) Oxygenated blood has more oxygen and less carbon dioxide than the tissue. 3. a) A – Water

Carbohydrates are made up of carbon‚ hydrogen‚ and oxygen. It provides energy for the body‚ especially the brain and the nervous system. The food sources are in sugar and grains. Lipids Lipids are made up of hydrogen‚ carbon and oxygen. It provides Energy storage‚ acting as structural components of cell membranes‚ and hormone production. The food sources are in fatty acids‚ dairy‚ and trygycerols. Proteins Proteins are made up of hydrogen‚ oxygen‚ nitrogen and carbon. It provides energy

aeneus is an organism that respires bimodally ‚ that it is being capable of drawing oxygen from both water and air. It carries out aerial respiration through it’s adapted posterior intestine.This experiment was done in order to determine the disadvantages of aerial respiration by manipulation of oxygen content and depth. The effect of dissolved oxygen‚ when the fish was placed into a cylinder of water and the oxygen concentration was determined while the number of breaths in a 10 minutes period was

Aerobic Treatment In the biological process‚ if the micro organisms (aerobes) use free or dissolved oxygen for the degradation of organic wastes‚ it is named as aerobic treatment. The availability of the oxygen for the working of aerobes as an electron acceptor accelerates the biodegradation significantly and maximized the treatment system capacity. Factors influence on treatment process The microorganisms and their growth are the driving force for the degradation process. To achieve a high rate

membrane through diffusion. Diffusion is the process of which the respiratory gases across the gas exchange membrane (oxygen from the environment into the body‚ carbon dioxide from the body to the environment). Using the concentration gradient along the gas exchange surface. For gas exchange to occur these three Features are needed; the gas exchange surface needs to be moist so that the oxygen and carbon dioxide can dissolve in water (H2O) in order to diffuse across the membrane. The gas exchange surface
