BIO1130 - Archean Eon Keywords - Shivan Desai Aerobic: Requiring oxygen to survive‚ and perform life functions. (Aerobe-Organisms that require oxygen for cellular respiration.) Aerobic respiration is a characteristic of eukaryotic cells‚ even though prokaryotic cells can use aerobic respiration as well. Helps produce allot of ATP. Example: Kreb’s Cycle. Anaerobic: Doesn’t require oxygen to survive and perform life functions. (Anaerobe-Organisms that don’t require oxygen to live)

Muscles do not continuously contract because the cross bridges are (prevented/allowed) to bind with the actin molecules. 19. When there is an action potential‚ it (acts on the contractile proteins directly/increases the cytosolic calcium concentration) 20. Increased calcium ions will bind onto (troponin/tropomyosin) binding site 21. An end-plate potential

Chapter 4 Tissue: The Living Fabric 4.1 What are tissues? * Groups of cells that are similar in structure and perform a common or related function * There are four basic types of tissues: 1) Epithelial (covering) 2) Connective (support) 3) Muscle (movement) 4) Nervous (communication and control) * The study of tissues is known as histology 4.2 Preparing Human Tissue for Microscopy Requirements * Specimen must be fixed (preserved) * Specimen must be

CHAPTER ONE INTRODUCTION/LITERATURE REVIEW THE ERYTHROCYTES A cell that contains haemoglobin and can carry oxygen to the body. Also called a red blood cell (RBC). The reddish colour is due to haemoglobin. Erythrocytes are biconcave in shape which increases the cells surface area and facilitates the diffusion of oxygen and carbon dioxide. This shape is maintained by a cytoskeleton composed of several proteins. Erythrocytes

Objectives Protein Isolation: Protein isolation for a western blot uses detergents and mechanical force to separate seeded cells from their container. Eukaryotic cells are attached to the surface of a flask by cadherins. In the past‚ we’ve separated the cells from the flask by breaking these bonds with a protease‚ but in order to keep the proteins intact‚ a different method needs to be used to extract the proteins. In protein extraction for a western blot‚ we use detergents to lyse the membrane
