types of lipids (purpose) correct answer: storage, structural, and signalling fatty acid chemical structure and charge correct answer: - fatty part is the carbon chain - acid part is carboxyl group (-COOH) - negatively charged which conformations of saturated fatty acids are most stable? correct answer: - anti conformation - extended conformation unsaturated fatty acids correct answer: double bonds are almost always in cis conformation which results in kinks in structure mono-...

Biomaterialsa material intended to interface with biological systems to evaluate, treat, augment or replace any tissue, organ or function of the body. Can also be a solid material that occurs in and is made by living organisms such as chitin, fibrin or bone. Exclusively used in healthcare. Can make biomedical devices out of biomaterials. Requires properties as close to physical properties of tissue (flexibility and texture), stability, degradable (rate and mode of degradation), biocomp...

What is the MAIN role of membranes and what are the other roles? - ANSWER - COMPARTMENTALISATION -site of chemical reactions -cell signalling -cell adhesion How do cell membranes compartmentalise? - ANSWER Membranes are hydrophobic layers that separate different regions of substances dissolved in water. This hydrophobic layer acts as a barrier preventing the movement of hydrophilic molecules from one region to another. It keeps one compartment separate from another. What are the 3 examp...

Topic 1 Introduction to Molecular Cloning 1. The goal of this integrated practical course is to purify a protein. In general, what is the value of protein purification to medical research? What information can a purified protein provide and what techniques can be developed/employed once you have a purified protein?  In vitro studies - Small molecule interactions, protein binding partners etc  Producing antibodies  Determination of structure Purification of the protein is a valua...

What does a nucleus do? - correct answer It contains genetic material and controls the activities of the cell What does cytoplasm do? - correct answer It's a gel-like substance where most of the chemical reactions happen. It contains enzymes that control these chemical reactions What does a cell membrane do? - correct answer It holds the cell together and controls what goes in and out What do mitochondria do? - correct answer These are where most of the reactions for aerobic respiratio...

Charles-Edouard Brown-Sequard Injected himself with ground-up animal testicles led to development of modern hormone therapy. Largely placebo Basic Principle of a Cell Signalling Pathway Stimuli -> Receptors -> Transducers -> Amplifiers -> Messengers -> Sensors and Effectors -> Cellular Responses (Fertilization, Proliferation, Differentiation, Secretion, Contraction, Metabolism, Membrane Excitability, Learning and Memory). Ligand Receptor Interaction A single ligand will b...
