AP Bio p. 6 December 8‚ 2011 AP Biology Lab 5: Cellular Respiration Introduction/Lab Objective: In this lab we are testing how the process of cellular respiration is affected by temperature‚ and also how it is different between germinating and non-germinating peas. Cellular respiration is a catabolic process (breaks down organic material into usable cell energy) that produces ATP. The electron receivers are inorganic. Cellular respiration releases energy from organic material through chemical

Biology SL – Chapter 4 questions Page 57 1. a) Difference between protein and polypeptide: Proteins have a structure formed by one or more polypeptide chains whilst a polypeptide is a chain of amino acids. b) Fat and oil differences: They are both lipids‚ but fats are solid whilst oil are liquids. c) Difference between starch and glycogen: Starch is a polysaccharide found in plant tissue whilst glycogen has polysaccharide found in animals. d) Condensation and hydrolysis:

With the evolution of animals living on land from animals living in the water‚ many changes needed to be made in order for survival. Each problem that these organisms may have experienced in the past has been dealt with a solution of some manner. One of the main problems was water storage. Because organisms in an aquatic environment are surrounded by water‚ they do no experience problems with water storage‚ but without an aquatic environment there are bound to be problems. The land organisms need

Practical 1- An experiment to observe the features of an Onion Cells Method: Gather all equipment that will be used for the experiment and check that they are clean and undamaged. Using forceps‚ peel the membrane from the underside of a small piece of onion. Place the membrane flat on a clean‚ glass slide and add one drop of iodine solution. Use a pin to carefully lower the cover slip over the slide‚ ensure there are no air bubbles before the use of the slide. Set the microscope to its lowest

Muscle Cell at rest: As the muscle cell is at rest it has a resting potential of -90mV. The K+ is all located inside the cell‚ the Na+ is located outside of the cell and the Ca2+ is located inside the sarcoplasmic reticulum. All leak channels and pumps are closed at this point. Muscle Cell stimulated by Acetylcholine: A motor neuron releases Acetylcholine which diffuses toward the muscle cell across the neuromuscular junction. As the Acetylcholine binds to a receptor on the muscle

Water has many unique properties that make life possible on Earth. One property is cohesion. The cohesion property is properly defined as the binding of water molecules by hydrogen bonds. Water has this property as a result of the chemical bonding between water. Cohesion of the strong hydrogen bonds allows the water molecules to stick together‚ almost as a unit of one. A force exerted on one of the molecules will be exerted on all of the adjacent molecules as a result of cohesion. Cohesion‚ often
