Food is any substance‚ usually composed primarily of carbohydrates‚ fats‚ water and/or proteins‚ that can be eaten or drunk by an animal or human for nutrition or pleasure. Items considered food may be sourced from plants‚ animals or other categories such as fungus or fermented products like alcohol. Although many human cultures sought food items through hunting and gathering‚ today most cultures use farming‚ ranching‚ and fishing‚ with hunting‚ foraging and other methods of a local nature included

activity. To measure the rate of oxygen consumption in germinating bean seeds. To determine the metabolic rates for several small animals and relate this to body size and lifestyle. Introduction All organisms‚ whether plant or animal‚ bacteria‚ protists or fungi‚ carry out cellular respiration. During respiration organic food molecules are oxidized and these exergonic oxidation reactions are coupled with the synthesis of ATP‚ an endergonic reaction. The ATP is then used to drive the metabolic reactions

Biology HL Portfolio The Cell and Cell Theory [pic] The cell The word cell comes from the Latin word “cellula”‚ which means a small room. The cell is the smallest unit of a living organism‚ also known as “the building block of life”. Every living organism is consisted of a cell. There are bacteria (unicellular organisms)‚ and multicellular organisms. There are different types of cells‚ prokaryotic and eukaryotic cells. All cells come from preexisting cells. “Every cell is self-maintaining;

ABSTRACT The glycolysis pathway is nearly universal in biological systems. Glycolysis is the sequence of reactions that converts glucose to pyruvate with the concomitant formation of ATP. Three fates of this pyruvate produced exist. In this practical the production of pyruvate and acetaldehyde by fermentation of glucose is established. A series of test tubes was set up each containing glucose and yeast suspension in buffers at different pH values. These test tubes were incubated for an hour at 37℃
