Structural Model of Antibodies

- August 19, 2021

Structural Model of Antibodies Antibodies are immune system-related proteins called immunoglobulins. Each antibody consists of four polypeptides, two heavy chains and two light chains joined to form a "Y" shaped molecule. The amino acid sequence in the tips of the "Y" varies greatly among different antibodies. This variable region, composed of 110-130 amino acids, give the antibody its specificity for binding antigen. The variable region includes the ends of the light and heavy chains. The constant region determines the mechanism used to destroy antigen. Antibodies are divided into five major classes, IgM, IgG, IgA, IgD, and IgE, based on their constant region structure and immune function. Role of Memory Cells in Immunity Neither the killer T-cells nor the B-cells just die off after they kill the pathogen. When their job is done, they leave behind memory cells. These memory cells are cells that stay behind and watch for the pathogen. If they find one...

Plant Movements and classification of plants movements

- July 14, 2021

Plant Movements Plant movements are usually too slow for the direct observation but the results are easily noticed e.g. the closing and opening of flowers,unfolding ofbuds, bending towards light,twining of tendrils, locomotion of Chlamydomonas and the gametes of algae, bryophytes and pteridophytes etc. dual natuce ye plant oc aswell Classification of Plant Movements Generally movement of plant parts can be classified according to the mechanism involved. Plants movements are classified into two major types;turgor movements and growth movements, rest of the classification of plantmovements is as under. (A)Turgor Movement Turgor movements are due to the differential changes in turgor and size of the cells as a result of the gain or loss of water and are easily And reversible. The effective cells are often different from ordinary cells and may be concentrated in certain areas. Petiole leaflets in normal position Petioledrooping Leaflets folded Pulvini at bases of leaflets.

Cardio vascular disorders

- August 18, 2021

Cardio vascular disorders, lymphatic system, open heart surgery Cardiovascular Disorders Many disorders are associated with the circulatory system. Some of the significant are the following. Thrombosis and Embolism Thrombus is a Greek word which means blood clot. It is formed by the aggregation of platelets inside the vessels. The disorder in which a person generates a thrombus in a vessel is called thrombosis. A thrombus in a blood vessel is very painful. A thrombus in a large blood vessel decreases blood flow through that vessel but in a small blood vessel it may completely stop the blood flow resulting in the death of tissue supplied by that vessel. Risk of thrombosis increases in certain conditions like atrial fibrillation, heart valve replacement, a recent heart attack, extended periods of inactivity. Sometimes genetic factors make a person more prone to thrombosis. Generally bed ridden patients and people like barbers who keep standing for hours as part of th...
