variables might have influenced the results in terms of the purity of each chemical or purity of the used filtrate. Background The chloroplast‚ basically‚ is the organelle responsible for photosynthesis. Structurally it is very similar to the mitochondrion. It contains a permeable outer membrane‚ a less permeable inner membrane‚ a intermembrane space‚ and an inner section called the stroma. However‚ the chloroplast is larger than the mitochondria. It needs to have the larger size because its membrane

Alkaline phosphodiesterase‚ Protease‚ Peroxidase and Mitochondrial Dehydrogenase. These enzymes were tested in three fractions which were obtained from a chicken liver cell namely the nuclei which contains the nucleus‚ microsome which contain the mitochondrion and other membrane bound organelles that are part of the endomembrane system and lastly the soluble which consists of the other organelles not mentioned above and different proteins. APDE‚ peroxidase and mitochondrial dehydrogenase were all incubated

ATP is produced in the last step where for every glucose only two are made outside the Mitochondria. At the same time another energy source is produced providing larger amounts of energy‚ this source is called pyruvic acid. This acid enters the mitochondrion where most of the energy is removed. As it enters the carbon is removed and by-product electrons‚ co-enzyme a clings to the remaining two carbons making acetyl CoA. (Dickey‚ Reese‚ Simon‚ 2010). * * What is the role of the citric acid

The outermost membrane is smooth while the inner membrane has many folds. These folds are called cristae. The folds enhance the "productivity" of cellular respiration by increasing the available surface area. The double membranes divide the mitochondrion into two distinct parts: the intermembrane space and the mitochondrial matrix. The intermembrane space is the narrow part between the two membranes while the mitochondrial matrix is the part enclosed by the innermost membrane. Several of the steps

through many stages of biochemical enzyme-catalyzed reactions. In more detail about the cycle its main purpose is to produce little amounts of ATP by removing carbon dioxide and hydrogen from pyruvate molecules. Within the inner membrane of the mitochondrion the electron transport chain and chemiosmosis synthesis ATP with hydrogen ions which are NADH and FADH2. The Krebs cycle and glycolysis produce less ATP because chemiosmosis synthesizes a great amount of ATP. In the electron transport chain

electron microscope by negative staining.[2] These are particles of 9 nm diameter that pepper the inner mitochondrial membrane. They were originally called elementary particles and were thought to contain the entire respiratory apparatus of the mitochondrion‚ but‚ through a long series of experiments‚ Ephraim Racker and his colleagues (who first isolated the F1 particle in 1961) were able to show that this particle is correlated with ATPase activity in uncoupled mitochondria and with the ATPase activity

Flag stands for Flagellum‚ the Flag is a locomotion oraganelle composed of microtubes. Mito is short for Mitochondrion‚ this is where the celluar respiration takes place and most of the cells ATP. Nuc is short for Nuclus or Nucleous ‚ the is used to produce ribosomes.Golgi stands for Golgi apparatus this organelle is in controlling the modification‚ sorting‚ and

The nucleus is a cell’s brain and operating system. The mitochondrion develops energy through cellular respiration. Ribosomes produce protein‚ while the nucleolus is what makes ribosomes. The vacuole is the largest organelle and it stores food‚ wastes‚ and water. The cell wall which is in all cells except animals

THE ROLE OF PROTEIN MISFOLDING AND AGGREGATION IN BSE When a protein misfolds it changes its behavior and function. If it becomes hydrophobic after once being polar. The properties and functionality of the protein are no longer useful to the organism and disaster results. PrPSc is hydrophobic‚ it avoids water inside of the cell…it attracts and attaches other proteins to misfolds and become hydrophobic …Misfolding spreads because the PrPSc act as chaperone proteins to convert PrPc TO PrPSc and

Mitochondrial DNA‚ or mtDNA‚ exists as a circular loop of double-stranded DNA rather than the linear form found in nuclear DNA. However‚ both forms of DNA are
