formula for cellular respiration is C6H12O6+ 6O2= 6CO2= 6H2O. The process of respiration contains three main parts‚ glycolysis‚ Krebs cycle‚ and the Electron Transport Chain. The process of glycolysis takes place in the cytoplasm and is considered an anaerobic process which splits glucose into two three-carbon molecules and makes two molecules of ATP. The Krebs cycle takes place in the interior space of the mitochondria and gives off carbon dioxide as a waste product when sugars are broken down. The

Lysosomes remove and digest wastes that include old cell parts and viruses and bacteria. They contain acid hydrolase enzymes. Lysosomes are formed from the golgi apparatus.

glucose oxidized Cellular respiration involves glycolysis‚ the Krebs cycle‚ and the electron transport chain. Glycolysis is a catabolic pathway that occurs in the cytosol and partially oxidizes glucose into twopyruvate (3-C). The Krebs cycle is also a catabolic pathway that occurs in the mitochondrial matrix and completes glucose oxidation by breaking down apyruvate derivative (Acetyl-CoA) into carbon dioxide. These two cycles both produce a small amount of ATP by substrate-level phosphorylation

steps: Glycolysis‚ the preparatory reaction‚ the Krebs Cycle‚ and the oxidative phosphorylation. Glycolysis occurs in the cytoplasm of the cell‚ in this process glucose is broken into two 3 Carbon molecules called pyruvates. The preparatory reaction occurs in the matrix of the mitochondria and in this reaction pyruvate get oxidized and attached to a coenzyme. The product is called acetyl CoA which is used to carry out the Krebs Cycle. The Krebs Cycle occurs in the matrix of the mitochondria‚

the input of two ATPs to produce two pyruvates‚ two NADHs‚ and 4 ATPs. The NADHs are synthesised when NAD+‚ delivered by B vitamins‚ become bound to hydrogen and energised electrons1. Following glycolysis is the Krebs cycle and electron transport chain respectively. The Krebs cycle uses the two pyruvates produced in glycolysis to make 2 ATPs per glucose and energy. This occurs through the oxidation of a pyruvate‚ wherein one of the three carbons will bond to oxygen and leave the cell as carbon dioxide

The Building Blocks of Life Worksheet Part 1: Mitosis and Meiosis Short-Answer Response Why are the process of mitosis and meiosis both important to a living organism? The process of mitosis and meiosis are both important to a living organism because without them a cell would not be able to reproduce. Mitosis is an asexual process used to replace old and dead cells with new ones by dividing into two identical daughter cells. Meiosis‚ however‚ is the step that makes sexual reproduction possible

Introduction: Cytochrome c oxidase plays a vital role in cellular respiration by accepting e- from cytochrome c and transferring them to an acceptor oxygen molecule in the final step of electron transfer chain. Carbon monoxide and cyanide are few of the inhibitor of this enzyme. 4 Fe2+ -cyt c + 8H+ + O2 4 Fe3+ -cyt c + 2H2O + 4H+ [out] Cytochrome c oxidase locates to the inner membrane which separates the mitochondrial matrix from the intermembrane space.
