Bacterial Energetics and Membranes Abstract The Mg2+/Ca2+ ATP synthase present in all bacterial membranes‚ particularly E. coli‚ couples ATP synthesis to the proton (H+) gradient produced by the ETC‚ a process known as oxidative phosphorylation. The gradient acts to power the ATPase‚ so that it may phosphorylate ADP to produce ATP. The reverse reaction of this process‚ or hydrolysis of ATP into ADP and Pi‚ may be used to observe ATPase activity when the resulting Pi is quantitatively measured

make some repairs if necessary. Mitosis is the process where by sister chromatids are split up to form two different cells. Once this has happened the whole process is free to start over making it a cycle. The Krebs cycle is a part of cellular respiration. It is a series of chemical reactions used by all aerobic organisms to generate energy. It starts with acetyl coenzyme A this is then converted into a number of carbon based sugars as various amounts of reduced NAD/FAD‚ ATP and CO2 are given off

nematodes and arthropods have a nonliving cuticle around their body and undergo ecdysis and molting. Procedure: Cytochrome-c oxidase is the amino acid sequence of a protein that is an essential component of the electron transport chain in aerobic respiration. Therefore it is present in all aerobic organisms and is a good tool to help with molecular phylogenetic studies. Each student in class was given certain organisms and they had to compare the organisms’ cytochrome-c oxidase sequences to look for

place to help release and convert energy. For example‚ sugars are converted to amino acids to make proteins‚ but in digestion‚ proteins are broken down into monomers of amino acid which then are converted into sugars. The process of cellular respiration is an example of chemical reactions. Throughout the chapter‚ the cell’s metabolism will be examined to understand how it controls the chemical reactions that take place in the cell.

Cell Fractionation: Isolation of Mitochondria from Cauliflower and Determination of Specific Enzyme Kinetics Introduction Mitochondria is an organelle found in eukaryotic cells that play a role in biochemical processes such as respiration and energy production. Mitochondria even play an important role in apoptosis‚ or programmed cell death. This is achieved by disruption of electron transport‚ oxidative phosphorylation‚ and ATP production or even the release of proteins that trigger activation

Increased production of CO2 is a result of increased temperatures acceleration of the rate of fermentation. Abstract: We have tested the affects of increased temperature above room temperature on the rate of fermentation of yeast. We had 6 flasks filled with 6mL DI water‚ 2mL Yeast suspension and 6mL glucose of which 3 were at 25°C and 3 were at 37°C. The flasks at 37°C had each mixture pre-heated at 37°C for 2 minutes before being combined and then added to the flask where it was put into the

REVIEW SHEET‚ EXAM 3 Chapter 6‚ Nutrition and Microbial Growth Define the four major modes of nutrition in microorganisms and distinguish among them in terms of energy and carbon sources The four major modes of nutrition are: 1. Photoautotrophs: (ex. Plants‚ some protozoa‚ & alegae) -microorganism which use carbon dioxide as a carbon source and light energy from the environment to make their own food. 2. Chemoautotrophs: -microorganism which uses carbon dioxide as a carbon source and
