denatured. Enzymes are involved in such processes as the breaking down of the large protein‚ starch‚ and fat molecules in food into smaller molecules during digestion‚ the joining together of nucleotides into strands of DNA‚ and the addition of a phosphate group to ADP to form ATP. The names of enzymes usually end in the suffix -ase. Enzymes are "biological catalysts." "Biological" means the substance in question is produced or is derived from some living organism. "Catalyst" denotes a substance

Abstract Carbohydrates are the most abundant organic compounds in the plant world. They act as storehouses of chemical energy (glucose‚ starch‚ glycogen); are components of supportive structures in plants (cellulose)‚crustacean shells (chitin)‚ and connective tissues in animals (glucosaminoglycans); and are essential components of nucleic acids (D-ribose and 2-deoxy-D-ribose). Monosaccharides‚ oligosaccharides‚ and polysaccharides are theclassifications of carbohydrates. This experiment involves

second to look at the big picture. Photosynthesis and cellular respiration are key ecological concepts involved with energy flow. Use Figure 9.2 to label the missing parts below. See page 163 of your text for labeled figure. Concept 9.1 Catabolic pathways yield energy by oxidizing organic fuels 1. Explain the difference between fermentation and cellular respiration. Fermentation is a partial degradation of sugars or other organic fuel that occurs without the use of oxygen. Cellular respiration

Xylitol additionally is valuable in recuperation after overwhelming activity on the grounds that the human body proselytes assimilated xylitol to glucose 6-phosphate and glycogen.

A: Acid Two acid groups of phosphoric acid are used in forming DNA bonds. DNA consists of a long chain of nucleotides which consist of 1. Deoxyribose (a 5-carbon pentose) 2. Phosphoric Acid 3.

To test if the unknown bacteria uses citrate as a source of carbon‚ Simmon’s citrate agar was used as the medium on which the bacteria was grown. The Simmon’s citrate agar consists of sodium citrate as the source of carbon‚ ammonium dihydrogen phosphate as the source of nitrogen along with pH indicator such as bromothymol blue. Procedure: The Citratase activity was detected by inoculating the unknown bacteria on the slant surface of Simmon’s citrate agar. Followed by overnight incubation at 37°C

The Carbon Cycle is a complex series of processes through which all of the carbon atoms in existence rotate. The same carbon atoms in your body today have been used in countless other molecules since time began. The wood burned just a few decades ago could have produced carbon dioxide which through photosynthesis became part of a plant. When you eat that plant‚ the same carbon from the wood which was burnt can become part of you. The carbon cycle is the great natural recycler of carbon atoms. Unfortunately

CHAPTER ONE INTRODUCTION The industrial attachment is an important part of the course structure of the university. This is the time students appreciate the theoretical work done in the lecture halls when seen practically. This attachment introduces the student to the outside world in terms of working experience and also prepares them for the future. The department of applied biology therefore introduced the industrial attachment program in its learning curriculum to give students a chance to combine
