Krebs Cycle

Submitted by bpmccarthy on Sun, 11/03/2019 - 21:06

Mitochondria are a cell organelle that are often referred to as "the powerhouse of the cell". This is due to their function of supplying the cell with energy in the form of ATP. ATP is produced as a result of many reactions carried out through the Krebs's cycle, also known as the citric acid cycle. The Krebs's cycle takes a glucose molecule and through many reactions involving electron transporters NAD+ and FADH. The final product of the Krebs's cycle brings energy in the form of electron carriers to ATP synthase, an enzyme that synthesizes ATP. The Krebs's cycle takes place inside the mitochondria, more specifically inside the mitochondrial matrix, which is located inside the inner membrane of the mitochondria. This membrane is important as it only allows the passage of carbon dioxide, water and oxygen, and facilitates proton transfer in order to make a proton gradient, which helps in the formation of ATP. The waste product in this cycle is CO, and is expelled from the body via gas exchange, where the body takes in oxygen for use in more cycles, as oxygen is an all-important final electron acceptor in the cycle. 



This was very infortmative but its structure could be changed. The paragraphs ideas do not flow from sentence to sentence,as it is confusing in parts what the Krebs cycle and NAD+ etc. have to do with eachother.
