Glycolysis

Cellular Respiration is a cycle that can be found in all living organisms. The significance of Cellular Respiration is that it creates energy by breaking down larger molecules. For instance, the breaking down of a glucose molecule through the Glycolysis cycle. Although, cellular respiration includes both aerobic, with oxygen and anaerobic, without oxygen processes. According to Campbell’s Biology Cellular Respiration is, “[t]he catabolic pathways of aerobic and anaerobic respiration, which break…

This step takes place in the cytoplasm of cells and is anaerobic which means it does not require the presence of oxygen. The runner eats a meal before the race and their body uses the glucose from the food to start glycolysis. In glycolysis the runner’s body takes the glucose and uses a little bit of ATP to convert it to pyruvic acid. The 6 CO2 molecules in glucose are split to make 2 pyruvic acid molecules each containing 3 CO2 molecules. The runner’s body converts the glucose…

The mitochondrion is an organelle which produces ATP or energy for all cells. The ATP produced by the mitochondria can be used to measure certain physical activities of fruit flies. In this experiment the development, climbing, flight, and in vitro activity of Drosophilia Melanogaster flies were tested. Three different strands of flies were used. One strand was the wild-type (wt) fly, which had normal mitochondria without any mutations. Another stand was the W501 strain (hybrid) which had…

produce ATP. These stages involve more complex chemical reactions than the other energy systems which is why ATP production is much slower. (The more complex the process - the longer it takes to produce ATP). The three stages are; Aerobic glycolysis (slow glycolysis), Krebs cycle (also known as the citric acid cycle) and the Electron transport chain. . An athlete who would use the lactacid system is a long distance runner such as Paula…

Respiration can take place with or without oxygen, however, in an anaerobic environment, fermentation occurs after glycolysis, and the reaction does not continue through the Krebs Cycle and ETC to produce ATP. Because CO2 is necessary for the production of ATP, this experiment measured CO2 production as an indicator of the presence of ATP. Carbon dioxide, the product…

for the variety A seedling. The process of cellular respiration will be slowed down because it no longer has the energy carrier. Cellular respiration requires NADH to return to NAD+ for glycolysis to take place. Without NAD+ being available to take the electrons in glycolysis, it will stop the process of glycolysis, electron transport chain, and Krebs cycle which will cause the rate of metabolism and oxygen consumption to drop. It will also stop the production of ATP because NAD+ is used in the…

For this reflection, I’m going to specifically focus on the morphological unknown lab we used 2-3 lab periods for. Before going into lab, I started to create my own dichotomous key for all the microbial species we’ve been working on, assuming we’d have a species we previously worked on. My dichotomous key went from from gram stain to respiratory use and to fermentation results. I quickly realized that I shouldn’t have been working on this as my first go to. I mentioned in a past reflection that…

in yeast. Organisms obtain the energy they need from food. Yeast cells use sugars, such as glucose, as a food source. However, because glucose cannot be used directly by organisms, glucose molecules have to go through the process of glycolysis. During glycolysis, one molecule of glucose gets broken down into two pyruvic acid molecules. Along with the two pyruvate…

It consists of several major pathways including glycolysis, pyruvate oxidation, the citric acid cycle and finally the electron chain transport. Glycolysis is a multi-step pathway that occurs in the cytoplasm of the cell where one glucose molecule is broken down into two pyruvate molecules. Glycolysis produces 4 ATP’s and 2 NADH. It uses 2 ATP’s in the process for a net of 2 ATP and 2 NADH. This process does not require oxygen…

require oxygen. There are two discussed types of fermentation: Alcohol Fermentation in which “glycolysis converts glucose in to pyruvate, producing NADH and FADH2, then pyruvate is broken down into CO2 and acetaldehyde. Acetaldehyde gains a hydrogen atom from NADH to form ethyl alcohol (ethanol) and thus completing the process.” Lactic Acid Fermentation is happens when “pyruvate produced by glycolysis gains a hydrogen atom from NADH to form lactic acid”.…
