4) Section 33 Yeast Cell Respiration 10/04/2010 Part B: Explanation of Results All cells carry out the process of cell respiration in order to meet their energy needs. It is advantageous for cells to have the ability to metabolize different substrates. In this experiment‚ we investigated each sugar’s (glucose‚ lactose‚ sucrose‚ fructose‚ and lactose/lactaid) cell respiration rate. When referring to my group’s graph and data‚ glucose ended up with the highest respiration rate (1‚177.2 ppm/min)

Seven characteristics of life In life‚ there are seven different characteristics these being; movement‚ excretion‚ respiration‚ reproduction‚ irritability‚ nutrition and growth. Below‚ I will explain each of the characteristics in detail. Reproduction means; “the production of offspring by a sexual or asexual process” (oxford concise colour medical dictionary‚ 2007). Animals and plants do this in different ways‚ animals need two parents‚ and therefore the offspring will share both of the parent’s

that is oxidized by aerobic respiration is because the NADH that is made in the cytosol during glycolysis cannot diffuse through the inner membrane of the mitochondrion‚ it must be transported into the mitochondrial matrix. So as a result the active transport of NADH consumes ATP releasing only 36 ATP molecules. 18) Anaerobic pathway differs from the pathways of aerobic respiration at the sites they occur in eukaryotic cells by the presence of oxygen. In anaerobic pathways the oxygen is absent

There is a limit to anaerobic respiration because of the lactic acid. The buildup of lactic acid will end up stopping the movement of the muscles are it beings to become painful.
