Chapter 6-Intro to Metabolism METABOLISM= all the chemical reactions in an organism CATABOLIC PATHWAY (CATABOLISM)• release of energy by the breakdown of complex molecules to simpler compounds EX: digestive enzymes break down food ANABOLIC PATHWAY (ANABOLISM) • consumes energy to build complicated molecules from simpler ones EX: linking amino acids to form proteins ORGANISMS TRANSFORM ENERGY ENERGY- capacity to do work KINETIC ENERGY- energy of moving objects POTENTIAL ENERGY- energy

INTRODUCTION Macromolecules are highly important organized organic molecules that are found within living cells. These biological molecules help the body execute precise important tasks. There are four types of macromolecules: carbohydrates‚ lipids‚ proteins and nucleic acids. (Karp‚ 2010) This specific experiment showcased the identification of different macromolecules using three different testing methods. Carbohydrates‚ sugar molecules‚ are known as “fast fuel” in the body‚ and they contain

Chronic inflammation has been shown to be a consistent pre-cursor to many metabolic diseases‚ such as obesity‚ fatty liver disease‚ atherosclerosis‚ insulin resistance‚ type II diabetes‚ degenerative disorders such as dementia‚ airway disease and some cancers.1 The relationship between diet‚ and more specifically refined carbohydrates‚ and chronic inflammation has been of high interest in the media in recent years. This interest could have a lot to do with the alarming rate that these metabolic

An investigation into the effects of glyphosate on a yellow meadow ants ability to chose a food source Abstract: Yellow meadow ants play a vital role in our ecosystem and this experiment looks at how glyphosate alters their decision making when choosing a food source. To analyse the ants choice making I used a choice chamber with one side containing banana without glyphosate and one side with the herbicide. I hypothesised that there would be more ants moving to the side without the glyphosate because

ethanol and carbon dioxide and is expressed chemically as: C6H12O6 + 2PO43- + 2ADP → 2C2H5OH + 2CO2 + 2ATP Behind this simplified chemical reaction is a series of complex biochemical reactions. These reactions (known as the ‘Glycolytic pathway’ or ‘Embden-Myerhof-Parnas pathway’) involve a number of enzymes and the reactions take place anaerobically inside the cells of brewing yeast. DB Breweries carry out this fermentation by a continuous process in which the beer moves through a series of stirred vessels

OBJECTIVE The objective of this lab was to determine the effects of two unknown drugs on the microtubule pathways in COS-7 cells through the process of immunostaining. METHOD Before arrival‚ the COS-7 cells were grown in culture dishes submerged in a growth medium that contained bovine serum. Two coverslips covered in the COS-7 cells were provided. After washing the coverslip with Phosphate Buffer Saline (PBS)‚ one coverslip was treated with the control solution‚ and the other was treated with
