A passive process‚ diffusion / osmosis is the movement of solute molecules from an area of greater concentration to an area of lesser concentration. 2. A solution surrounding a cell is hypertonic if: a. it contains fewer nonpenetrating solute particles than the interior of the cell. b. it contains

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 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

Sebastian Krug‚ s082349 New Economy Transport 1 1 NET (A) - Question 1 As you can see on the rst spreadsheet the NPV of the overhaul with the new engine and control system (1:117:413; 38 Euro) is higher than the NPV without the new stu (480:211; 75 Euro). In this case Mr. Handy should choose the overhaul with the new stu . First of all the entire calculation is in real numbers. I’ve done it in nominal numbers too (with the same results) but it was too much to hand in. The assumptions I’ve

Cell Transport And Homeostasis The roles of different types of cell-membrane proteins in the preservation of body organs donated for transplant is very vast. Certain cell-membrane proteins carry several different types of nutrients that are beneficial and are sometimes very important to keep organs that are to be transplanted healthy and fresh. Organic nutrients are some very good preservers. One of the most transplanted organs is the kidney. It is important that this organ has nutrients

Water Transport in Plants Introduction In this lab experiment‚ we set out to examine the different transpiration rates of a plant system in certain environments. Water is transported in a plant by the process of transpiration‚ which is the loss of water through evaporation from the surface of leaves. The stomata in leaves are responsible for the diffusion of water vapor. Transpiration brings water upward through the xylem in the plant. There are certain factors that can affect transpiration
