prokaryotic cells. It has three main stages: glycolysis‚ the citric acid cycle‚ and electron transport. Stage one glycolysis means the “splitting of sugar”. Glycolysis is a six carbon glucose molecule which is then broken in half‚ forming two three carbon molecules. The initial split requires an energy investment of two ATP molecules per glucose. Then the three carbon molecules donate high energy electrons to NAD+‚ the electron carrier forming NADH. Glycolysis then makes four ATP molecules when the enzymes

Cellular respiration is indeed a lengthy process‚ especially just to make ATP (energy)‚ and it all starts with a glucose. The first process to cellular respiration is glycolysis‚ which can be literally translated to the breaking of glucose. To note‚ glycolysis takes place in the cytoplasm of the cell. There are two parts to glycolysis: the “investment” phase and the “harvest” phase. With the aid of two ATP‚ the first enzymatic reaction in the “investment” phase is basically twisting the glucose molecule:

minutes. All of the sugars produced energy‚ but glucose was the most efficient of the three‚ even producing energy at three times the rate of fructose. This difference in efficiency is a result of the various pathways the sugars must take to enter glycolysis. Glucose could enter directly while sucrose had to be broken down and fructose required modification to enter as an intermediate. Introduction Respiration makes up a cell’s metabolic process where carbohydrates are converted into energy

into energy these pathways are called glycolysis‚ the Krebs cycle‚ and electron transport. I would like to focus on the two common pathways; glycolysis and the Krebs cycle. Glycolysis is a series of reactions that convert glucose into pyruvate and help with the production of ATP. This process is anaerobic‚ which means that oxygen is not present‚ nor is it needed. The reactions happen within 3 phases and a total of 10 steps. The first phase of glycolysis is sugar activation. This is where the
