Aim: To study the agglutination pattern of different strains of Psuedomonas aeruginosa to different sialic acid-binding lectins. Absract: The cell membrane of two strains of Psuedomonas aeruginosa‚ P22 and P201 were treated the sialic acid lectins SNA I‚ WGA‚ MAL and HAA to confirm the presence of sialic acid carbohydrates in the cell surface membranes of these strains. This was done by using two sets of samples-one treated with trypsin and the other without. The sample treated with trypsin showed

Biology I Cell Biology Review 1. What are the four basic parts that all cells must have? 2. Draw a simple rod-shaped prokaryote with these features: Cell membrane‚ cell wall‚ cytoplasm‚ DNA‚ one plasmid and ribosomes. Which feature is unique to bacteria? 3. How might you tell the difference a prokaryotic cell from a eukaryotic one? Which is the most primitive? Which is the most complex? 4. What organisms are classified as prokaryotes? 5. Know all the organelles we covered and their

RESTING POTENTIAL Resting potential is the membrane potential when a neuron is not conducting any electrical impulse or signal. The resting potential is around -75 mV. During resting potential‚ the inside of the axon is negative GRADED POTENTIAL ACTION POTENTIAL Action potential is a fleeting reversal of the membrane potential‚ caused by changes in permeability of the plasma membrane of neuron to potassium and sodium ions causing an electrical impulse to be transmitted along the axon.

will convey across the membrane of an egg”. Furthermore‚ the egg was placed into three differing solutions‚ maple syrup‚ tap dihydrogen monoxide‚ and brine‚ to illustrate that “depending upon the concentration of dihydrogen monoxide in an egg and that in its circumventing environment‚ dihydrogen monoxide may diffuse into or out of the egg”. In summation‚ to genuinely understand the lab and make a plausible prognostication one must first grasp the concepts of the cell membrane as a semi-permeable barrier

exclusively by the pancreatic beta cells. These beta cells are located in the pancreas in clusters known as the islets of Langerhans. Insulin is a small protein produced as part of a larger protein to ensure it folds properly. In the protein assembly of insulin‚ the messenger RNA transcript is translated into an inactive protein called preproinsulin. Preproinsulin contains an amino-terminal signal sequence that is required in order for the precursor hormone to pass through the membrane of the endoplasmic reticulum

The theme of this assignment is to explore the complex medical condition‚ anaphylaxis. Anaphylaxis is a severe allergic reaction that is potentially fatal. It is the clinical manifestation of a syndrome that represents the most severe allergic reaction affecting the systemic circulation and respiratory function (Resuscitation Council UK‚ 2005). Through a comprehensive examination of the symptoms displayed in the case study‚ a clear diagnosis will be recorded. Connections will be balanced between

Overview: Life at the Edge The plasma membrane separates the living cell from its nonliving surroundings. This thin barrier‚ 8 nm thick‚ controls traffic into and out of the cell. Like all biological membranes‚ the plasma membrane is selectively permeable‚ allowing some substances to cross more easily than others. Concept 7.1 Cellular membranes are fluid mosaics of lipids and proteins The main macromolecules in membranes are lipids and proteins‚ but carbohydrates are also important. The

The mouth: salivary alpha enzyme chew food‚ perceive taste‚ moisten food with saliva‚ lubricate food with mucus‚ release starch –digesting (amylase) enzymes‚ initiate swallowing reflex - Enzyme: alpha amylase with cooked starch as substrate – starch digestion enzyme an enzyme that catalyses the breakdown of starch into sugar - The Functions of Saliva - 1. Moistens and lubricates food‚ permitting swallowing 2. Holds taste producing substances in solution and bring them in
