Gluconeogenesis

Glucose is then permitted entry into the cell by the process of facilitated diffusion, and can be used to produce ATP. Insulin

Selected Answer: C. glycolysis Answers: A. glycogenesis B. glycogenolysis

The substrate for beta-galalactoside is ortho-nitrophenyl-B-galactoside. ONPG is structured similarly to lactose. The purpose of the experiment was to add a competitive inhibitor to observe if the reaction rate would slow down. A competitive inhibitor is when the inhibitor binds to the active site on the enzyme and prevents the binds of the substrate

The Krebs cycle breaks the pyruvate from the glycolysis which becomes ATP. Another difference is how many ATP they each produce. Glycolysis produces 2 ATP and the Krebs cycle makes about 36 to 38 ATP. Energy metabolism is regulated by long chain fatty acids and ADP. Calcium, ADP, and NAD+ are activators.

In order for our body to use the glucose, it must enter into our cells first. The pancreas produces a hormone called insulin, a chemical messenger for the entry of glucose into the cells. As the blood glucose levels rise after a meal insulin is released into the bloodstream and sets process into motion to trigger glucose to enter into the cells. When the glucose enters into the cells the amount of glucose in the bloodstream

After that, a spin vane was inserted into the vial while adding 0.75 mL of 1M H2SO4 solution. During the addition of the sulphuric acid, the solution was stirred at room temperature until the amino acid (L-Phe) completely dissolved. An ice bath was prepared and used for cooling the L-Phenylalanine solution at a temperature of 40C (a selected temperature lower than 50C). Once the solution was cooled, the first portion

This is the second step. During fermentation, from a rough dense mass lacking extensibility and with poor gas holding properties, the dough slowly changes into a smooth, extensible dough with good gas holding properties. As the yeast cells grow, the gluten protein pieces clump together to form networks. Hence, the alcohol and carbon dioxide are formed from the breakdown of carbohydrates that are found naturally in the flour. Enzymes present in yeast and flour also help to speed up this reaction.

Dependent Variable amount of product (glucose and fructose) produced 2. Independent Variable temperature 3. Controlled Variables pH, amount of substrate (sucrose) present, sucrase + sucrose incubation time Effect of Substrate Concentration on Enzyme Activity 1. Dependent Variable amount of product (glucose and fructose) produced 2.

The pyruvate molecules that were created in glycolysis are then sometimes fermented into lactic acid. Lactic acid can be used to transform lactose into lactic acid, for example in the making of yoghurt. This process is also used in animal muscles when they require extra energy in their tissue in order to run faster than oxygen can be given. C6H12O6 (glucose) > 2CH3CHOHCOOHc*lactic acid) is the net equation for glucose to lactic acid.

B-galactosidase breaks down the disaccharide lactose into simple sugars glucose and galactose. However, glucose is a colorless compound hence it has to be substituted with a compound that is detectable by a visible color change. Hence,

The Effect of Sugar Concentration on CO2 Production by Cellular Respiration in Yeast Introduction In this lab, our main focus was to find how sugar concentration affect yeast respiration rates. This was to simulate the process of cellular respiration. Cellular respiration is the process that cells use to transfer energy from the organic molecules in food to ATP (Adenosine Tri-Phosphate). Glucose, CO2, and yeast (used as a catalyst in this experiment) are a few of the many vital components that contribute to cellular respiration.

Due to our main element involving the production of carbon dioxide, alcoholic fermentation will be further explained. This process involves yeast, a single celled fungus to produce ATP. These cells undergo the process of Glycolysis and then convert both pyruvates into molecules of ethanol. Ethanol, being a 2- Carbon molecule proves that the lost carbon was given off as carbon dioxide into the

Fermentation uses more glucose because the process of fermentation is much less efficient than cellular respiration in terms of energy production per molecule of glucose used. The open flask (control) and the closed

Role of Enzymes in Metabolic Pathways Summary Metabolic pathways are a sequences of steps found in biochemical reactions in which the product of one reaction is the substrate for the next reaction [3]. Metabolic pathways most likely happen in specific locations in the cell. The control of any metabolic process depends on control of the enzymes responsible for the reactions occur in the pathways. After food is added to the body, molecules in the digestive system called enzymes break proteins down into fats into fatty acids, amino acids, and carbohydrates into simple sugars (for example, glucose). Enzymes plays an important role in the different metabolic pathways [5].

• Carbohydrate metabolism: • Gluconeogenesis: The formation of glucose from certain amino acids, lactate and glycerol. • Glycogenolysis: The formation of glucose from delglucógeno. • Glucogenosíntesis: The synthesis of glycogen from glucose. • Elimination of insulin and other hormones.
