The objective of this experiment was the synthesis of Isopentyl Acetate using an esterification reaction between acetic acid and Isopentyl Alcohol‚ using a strong acid as a catalyst. The product was washed‚ and distilled. This approach is called Fisher esterification‚ whereby esters are produced by the esterification of a Carboxylic acid where it is heated with an alcohol in the presence of a strong acid which acts as a catalyst. The ester produced had a banana flavor. The extraction of the

at the start of any activity‚ even if the intensity is not enough for the aerobic system. If you go out on a jog‚ most of this is powered by the aerobic system‚ but the start of the jog is needs to create ATP so that the heart and lungs have enough oxygen and can saturate the blood before the aerobic system can kick in. When the heart and lungs have caught up with the movement of the activity and the intensity is low enough‚ then the aerobic energy system can fuel the body. In bas scenarios‚ such

Assuming Joseph’s heart stopped‚ what cellular functions are going to be affected by the loss of oxygen‚ blood glucose‚ and waste removal? All cells will work hard burning up ATP. Carbon dioxide starts to build in cells and PH balance will drop. Cells will die and active transport pumps shut down the plasma membrane of his heart. Cell become leaky

presence of suspended solids in water which reduces penetration of light‚ resulting in a decrease concentration of oxygen. Acidity is the concentration of hydrogen ions in the water body. A pH of 5.5-7.5 (meaning slightly basic water) is preferred in water supplies. Dissolved oxygen is the measure of oxygen dissolved in aqueous solution whilst biochemical oxygen demand is the measure of oxygen used by organisms. Both of these are monitored to prevent harm caused to bacteria and organisms. Natural Factors

RESPIRATORY SYSTEM OBJECTIVE QUESTION 1) High-flying birds are able to obtain enough oxygen even when the air is very thin because A) they have more efficient lungs than other vertebrates. B) they have reduced amounts of hemoglobin in their blood. C) their mitochondria are more efficient than those of other vertebrates. D) their heart can increase or decrease in size as altitude changes. E) they are able to store oxygen in oxygen chambers within muscle cells. 2) If you were to move from around sea level to

is from paleocimatologists look at bubbles of air trapped in the ice‚ which contain samples of the atmosphere from that time period. Paleocimatologists observe the oxygen in the ice\water molecules. Most of the oxygen atoms are in two forms called isotopes the two different isotopes are 18o and 16o which stand for 18-oxygen and 16-oxygen. The proportions of these two are really similar but different 18o is slightly heavier than 16o. The proportions of these two isotopes depend on the average temperatures

The respiratory system also has importance in the body as it is the system to transport air into the lungs to aid the diffusion of oxygen to the blood.The primary functions of the cardiovascular and respiratory systems is to provide the body with nutrients and oxygen and get rid of waste products such as carbon dioxide. During short term exercise stimulus there is a significant change in heart rate‚ blood pressure and respiratory rate as it adapts
