    ABSTRACT The effect of inorganic cofactor such as Magnesium to the rate of respiration of yeast was determined using Durham tube assembly with the substrate glucose. After thirty minutes‚ the test tube with the cofactor in the form of Magnesium sulphate MgSO4 showed the higher amount of carbon dioxide evolved which was measurable through volume and was one of the by- products of cellular respiration. This stated that the higher amount of CO2 evolved‚ the higher the rate of respiration. Thus‚ the

    ketone or aldehyde functional groups).  The groups reduce CuSO4‚ a component of Benedicts‚ resulting in a color change in the benedicts solution from a turquoise to a brick to rusty-brown color. Another class of carbohydrates called starches‚ a polysaccharide‚ can be detected using the Iodine’s test. Having a high molecular weight‚ iodine attaches to the helical structure of starches  yielding a blue-black precipitate. The Biuret’s test identifies proteins by oxidizing 4-6 peptide bonds of a protein

    1. The Structures of the Human Heart The human heart has four chambers: two ventricles‚ each of which is a muscular chamber that squeezes blood out of the heart and into the blood vessels‚ and two atria‚ each of which is a muscular chamber that drains and then squeezes blood into the ventricles. The two atria reside at the top of the heart; the two ventricles are at the bottom. And‚ the heart is divided into left and right halves‚ so there is a left atrium and left ventricle‚ as well as a right atrium
