Science 1. A‚ because organisms need carbohydrate‚ vitamins‚ and minerals and other nutrients to gain energy and proteins to live and to continue metabolism. B‚ The amount of energy stored in macromolecules varies because their chemicals structures‚ and there for the energy contain in their chemical differ. 2. 6O2 + 62H1206 -> 6O2 + 6H2O + Energy B The process of cellular respiration provides the energy a cell needs to carry processes‚ which in turn control the cell’s internal conditions.

CHAPTER ONE 1.0 INTRODUCTION The student industrial work experience scheme (SIWES) is a skill training program which forms part of the approved minimum academic standards in the various degree (diploma or NCE program for all Nigeria tertiary institution). It seeks to bridge the gap existing between theory and practice of engineering‚ technology science and other professional education in the Nigeria tertiary institution. 1.1 PURPOSE OF SIWES The purpose of SIWES is to expose students

that produces pyruvic acid. The pyruvic acid then undergoes a fermentation process to produce ATP‚ which cells employ for energy production. In this lab‚ anaerobic respiration in yeast was experimented. The formula for anaerobic respiration in yeast is C6H12O6 energy+ 2C2H5OH+2CO2. Yeast is a single celled fungus containing a number of enzymes useful during fermentation such as zymase. Zymase is an enzyme that catalyzes the fermentation of sugar into ethanol and carbon dioxide. Yeasts are eukaryotic

DIFFERENT TYPES OF AGAR Mac Conkey‘s Agar plate MacConkey (also McConkey) agar is a culture medium designed to grow Gram-negative bacteria and stain them for lactose fermentation. It contains bile salts (to inhibit most Grampositive bacteria‚ except Enterococcus and some species of Staphylococcus)‚ crystal violet dye (which also inhibits certain Gram-positive bacteria)‚ neutral red dye (which stains microbes fermenting lactose)‚ lactose and peptone.

was the Carbohydrate fermentation broth test. The reason for doing this test was to identify the bacteria by determining what nutrients they can utilize and what end products will be produced in the process. “Sugars such as glucose will undergo "fermentation" when it acts as an electron donor‚ such as in glycolysis‚ and one of its metabolic products (such as pyruvate) acts as an electron acceptor in a fermentation reaction”. Most sugars other than glucose are said to undergo fermentation" when it

This lab was completed to determine the rate in which fermentation occurs in different sugars and to compare the rate of cellular respiration in germinating and non-germinating soybeans. Fermentation breaks down sugars for a source of energy. Cellular respiration is the process used by cells to produce energy from nutrients. This process allows sugars and foods to be broke down in order to obtain energy from adenosine triphosphate (ATP). Cellular respiration is vital for survival of cells. Oxygen

The Great Metabolic Race Metabolism comprises of a vital set of biochemical reactions that all living organisms require to sustain life. For a marathon runner‚ their physiological response to strenuous exercise depletes both their fats and carbohydrate storage in order to supply energy in the form of Adenosine Triphosphate (ATP). ATP is the energy form that the human body uses for biological processes such as movement and synthesis of biomacromolecules. In regards to running a marathon‚ the athlete
