Chapter-1 • Introduction • Concept of Transport • Functions of Transport • Means of Transport • Transport in India ix 1.1 INTRODUCTION From the beginning of history‚ human sensitivity has revealed an urge for mobility leading to a measure of Society’s progress. The history of this mobility or transport is the history of civilization. For any country to develop with right momentum modern and efficient Transport as a basic infrastructure is a must. It has been seen throughout the history

Estimating Osmolarity of Plant Cells Criteria Assessed: DCP Introduction In this experiment you will be estimating the osmolarity of potato cells by finding their change in weight in solutions of known molarity. The object is to find the molarity where the mass does not change. No net change in weight indicates that there has been no net gain or loss of water. This is a means of indirectly finding the osmolarity of the cells themselves. Apparatus 1 large potato Petri dish 7 x 250 ml beakers

12. Briefly discuss the role of the electron transport chain in cellular respiration. In your explanation‚ discuss and identify key molecules involved in this process and explain their relationship which each other in terms of how they contribute to the main cellular purpose of this process. Electron transport chain plays a key role of in the production of oxygen in cellular respiration. ETC uses many enzymes located on the inner mitochondrial membrane during the production of oxygen.

Active and passive transport are biological processes that move oxygen‚ water and nutrients into cells and remove waste products. Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration. On the other hand‚ passive trasport moves biochemicals from areas of high concentration to areas of low concentration; so it does not require energy. Comparison chart Active Transport Passive Transport Definition Active

Active transport: requires that a cell expend energy to move molecules across a membrane against the solute’s concentration gradient (the side where it is more concentrated) Feedback inhibition: Metabolic reaction is blocked by its products. A product acts as an inhibitor of one of the enzymes in the pathway to regulate metabolism. Centriole: a structure in an animal cell composed of microtubule triplets arranged in a 9+0 pattern. An animal usually has a pair of centrioles within each of its centrosomes
