Enzyme Lab Marcus James. December 20‚ 2013 HL Biology 3 Period 1 Purpose and Background The purpose of this lab is to explain how enzymes act as catalysts for biological reactions in different temperatures. This lab relates to enzymes‚ proteins‚ and substrates; that we learned in class. The union of the enzyme and the substrate is called the enzyme-substrate complex. The make-up of an enzyme is proteins and made up of chains and amino acids. Enzymes

BKristen Gershkoff Mr. Zabel Ecology 1 October 2012 How Abiotic Factors Affect the Biota The variation of abiotic factors in both the beach and the salt pond greatly affect the biota in those areas. At the beach there was a rocky landscape that rounded the water‚ while at the salt pond‚ there was more of a wet grassy area allowing different life forms or biota to thrive in each. Also‚ physical factors such as temperature‚ salinity‚ or dissolved oxygen levels allow for different life forms to

P2 – Factors that affect development. There are five main factors that affect a person’s development‚ they are: Genetics factors. Environmental factors. Socio-Economical factors. Life style factors. Biological factors. Genetic factors Each cell in the body contains 23 pairs of chromosomes‚ half from your mother‚ and half from your father. The chromosomes contain the genes you inherit from your parents. For example‚ for the gene that determines eye colour you may inherit a brown gene and a blue gene

experiment was to investigate the effect that a glucose concentration has on the rate of fermentation. This was done by adding a variety of different glucose concentration into a test tube‚ siting in a water bath. The carbon dioxide would be collected in the test tube and therefore would measure the rate of fermentation. The results parsley supported the hypothesis that‚ “If the glucose concentration increases‚ the rate of fermentation increases‚ therefore the more carbon dioxide released”. Background

Research Question: How does the number of sit-ups affect your heart rate. Independent Variable (IV): Number of sit-ups ( 0‚5‚10‚15‚20). I chose these 5 increments because they are consistent numbers in which everyone can participate without it being to much. Dependent Variable: heart rate( BPM) +/- 4 ( number of beats in 15 seconds multiplied by 4). Materials: timer‚ flat surface‚ movable clothing Background: In this experiment I will test your heart rate and if it increases or decreases with exercise

Investigation into the photosynthetic activity of isolated chloroplasts from spinach beet to various light conditions. Introduction Chlorophyll‚ an important pigment in chloroplasts‚ is an essential component in photosynthesis; converting electromagnetic radiation from the sun into potential chemical energy. Photons excite electrons in chlorophyll which move through the electron transport chain‚ resulting in energy being stored in the bonds of ATP and NADPH. The flow of electron through the electron
