Cell Biology (PCB 3023) Fall 2012 Review for Exam 1 Chapter 1 List the key commonalties and differences between prokaryotic and eukaryotic cells. Prokaryotic – no organelles; no nucleus; bacteria and Achaea; spherical‚ rodlike/corkscrew-shaped; cell wall; Eukaryotic – has nucleus; has organelles Commonalities – contain DNA that stores genetic information What is the main component of cellular membranes? What function(s) do membranes serve in cells? Made of phospholipids; defines

Abstract Enzymes are biological catalysts that speed up the rate of chemical reactions by lowering the reactants’ activation energy. The goal of this lab was conducted to determine the optimal temperature for bacterial and fungal Amylases and evaluate how temperature affects the catabolic rate of enzymes. Enzyme reaction rate was measured using an Iodine test in which drops of starch solution with either fungal or bacterial Amylase exposed to different temperatures were mixed with Iodine. Iodine

Quercetin (2-(3‚4-dihydroxyphenyl)-3‚5‚7-trihydroxy-4H-chromen-4-one) is a flavonoid which is a group of pigments that give many flowers‚ fruits‚ and vegetables their colour (Askari et al. 2012). Before supplement use became more prevalent the nutritional status of an individual was determined by the contents of their diet‚ and many of the people with a high nutritional status typically consumed a high amount of fruits and vegetables. Fruits and vegetables are the primary dietary sources of quercetin

carrier of chemical energy in all living organisms. It consists of adenine linked to D-ribose (i.e. adenosine); the D-ribose component bears three phosphate groups‚ linearly linked together by covalent bonds (see formula). These bonds can undergo hydrolysis to yield either a molecule of ADP (adenosine diphosphate) and inorganic phosphate or a molecule of AMP (adenosine monophosphate) and pyrophosphate. Both these reactions yield a large amount of energy (about 30.6 kJ mol–1) that is used to bring about

BIOFERTILIZER: The pathophysiology of the Tuberculin reaction is explained thus: M. Tuberculi are engulfed by macrophages after being identified as foreign‚ but due to a self- preserving mechanism peculiar to TB it is able to block the fusion of the phagosome within which it is existing with the lysosome which would destroy it. So it can continue existing and replicating within the immune cell designed to destroy it. After several weeks‚ the immune system somehow [ mechanism as yet unexplained]

Treating starch How is starch and cellulose treated to allow them to be used by the yeast? (1)Starch is a complex carbohydrate that is insoluble in water. It is supplied by traditional staple foods such as cereals‚ roots and tubers. Starch is used in cooking for thickening foods such as sauce. In industry‚ it is used in the manufacturing of paper‚ textiles and as a mould in the manufacture of sweets such as wine gums and jelly beans. Fermentation (2)As with any food preparation‚ there are

Biology‚ is the study of living things. In biology there are many branches that all contribute to life. Those branches of life aid each other’s function to maintain their function. In photosynthesis and aerobic cellular respiration energy is being produced to cycle carbon between the functions. There is the function of maintaining life‚ helping aid chemical reactions‚ using the cell to help aid reation. All of these recycling processes help creates energy that is then in return used to aid their

of three components; head domain binds actin filament and ATP‚ hinge region binds to myosin light chains and functions as the lever arm and tail domain it interacts with other myosin tails or with intracellular cargoes. The joint work of the ATP hydrolysis allows the myosin to produce mechanical force. Myosin is a thick contractile protein that is a motor molecule that works to move the cells in the muscle that contribute to the muscles contracting. It works with the protein actin that combines to
