1. Explain the difference between a peptide bond and a sulfide bond. Draw an example of each. (Insert a picture of your drawing of the molecule or a scan of your drawing of the molecule) A peptide bond is a covalent bond. This bond is between two amino acid molecules. The formation of a peptide bond occurs when a carboxyl group present on one molecule reacts with an amino group that is present on the molecule. This reaction releases H2O. In organic chemistry‚ I learned that a sulfide bond has to

3 STAGES OF CELLULAR RESPIRATION GLYCOLYSIS Glycolysis is the first of the three steps used to breakdown glucose to produce ATP. Glucose‚ a 6 carbon sugar‚ is split into two 3 carbon sugars. The 3 carbon sugars are then oxidized and their remaining atoms reaarranged to form two molecules of pyruvate. There are 2 distinct phases of Glycolysis: 1.PREPARATORY PHASE: Energy in glucose cannot be readily released unless energy from ATP if

What occurs during glycolysis? Molecule of glucose is split‚ two molecules of Pyruvic Acid are made‚ and 2 ATP’s are produced. Is glycolysis an aerobic or anaerobic reaction? anaerobic 28. What is the process that takes place when organic compounds are broken down anaerobic (without oxygen)? fermentation 29. What is produced in muscles when you exercise vigorously in the absence of necessary oxygen? Lactic Acid 30. Name the three stages of cellular respiration. Glycolysis‚ Krebs (Citric Acid)

process by which cells obtain energy from glucose. Cells are broken down into simple food molecules. Cellular Respiration undergoes two processes: Glycolysis and The Krebs Cycle. In Glycolysis enzymes help in chemical reactions that break down oxygen and glucose into different molecules. Pyruvic and 2 molecules of ATP are produced during Glycolysis. In the Krebs cycle nine reactions occur. Pyruvic acid is broken down and carbon dioxide and energy are given off. This energy is then used to create

How is pyruvic acid changed to acetyl co-A? b. When pyruvic acid is changed to acetyl co-A‚ is it being oxidized or reduced? 8. Summarize all of the important products (and their quantities) yielded after one pyruvic acid molecule “leaves” glycolysis and goes through the acetyl co-A formation stage. 9. What

Benjamin Tiger1/16/12 Cellular Respiration Questions 1. Aerobic pathways require oxygen‚ while anaerobic pathways don’t. Anaerobic pathways only require the process of glycolysis to produce energy. Anaerobic pathways are found outside the mitochondria within the cytoplasm of the cell‚ with a low efficiency of 4%. These pathways require glucose‚ ATP‚ adolase‚ fructokinase‚ dehydrogenase‚ and NAD+. Out of one glucose molecule‚ major products include two net ATP‚ two NADH‚ and two pyruvate

infoldings of the inner membrane)‚ and the matrix (space within the inner membrane). Summarize the steps and outcomes of glycolysis In glycolysis‚ glucose (sugar) is "burned" in the presence of oxygen to produce energy in the form of ATP. Carbon dioxide and water are they by-products. Describe the steps of the Krebs cycle and its outcomes The pyruvate molecules produced during glycolysis contain a lot of energy in the bonds between their molecules. In order to use that energy‚ the cell must convert it

Before the experiment‚ we made some hypotheses based on predictions questions. First‚ yeast will metabolize sugar and produce a gas. This is because yeast is a living organism and all living organisms like yeast must use energy (such as sugar) to obtain energy. Yeast will metabolize sugar and gives off carbon dioxide as a by-product. For the second hypothesis‚ we were expecting that yeast will produce a gas when sugar is available. For the third hypothesis‚ we did not expect yeast to produce
