affect the beetroot cell membrane‚ I will keep the temperature constant throughout the experiment by using a water bath and measuring the desired temperature using a thermometer. PH: I will make sure that the pH is stable (constant) and only the temperature varies this is to be done by using buffer in every test tube so as to maintain pH balance for each beetroot sample and insure that pH does not become a variable. PH is important for maintaining the integrity of the cell membrane as integral proteins

Bacterial Energetics and Membranes Abstract The Mg2+/Ca2+ ATP synthase present in all bacterial membranes‚ particularly E. coli‚ couples ATP synthesis to the proton (H+) gradient produced by the ETC‚ a process known as oxidative phosphorylation. The gradient acts to power the ATPase‚ so that it may phosphorylate ADP to produce ATP. The reverse reaction of this process‚ or hydrolysis of ATP into ADP and Pi‚ may be used to observe ATPase activity when the resulting Pi is quantitatively measured

Transport Across The Plasma Membrane Intracellular Fluid (ICF) – The two thirds of your body fluid contained inside body cells. (Intra = within). The cytosol of the cell. Extracellular Fluid (ECF) – Fluid outside the body cells. (extra = outside). Interstitial Fluid – The ECF in tiny spaces between cells (inter = between). Plasma- the ECF in blood vessels. Lymph- The ECF in lymphatic vessels. Solute – Any material dissolved in fluid. Solvent- The fluid a Solute is dissolved in. Concentration

Resting membrane potentials Definition: Large nerve fibers when not transmitting nerve signals is about 90 millivolt. That is‚ the potential inside the fiber is 90 millivolts more negative than the potential in the extracellular fluid on the outside of the fiber. The Na+-k+ pump also causes large concentration gradients for sodium and potassium across the resting nerve membrane. These gradients are the following: Sodium ( outside): 142 mEq/L Sodium ( inside): 14 mEq/L Potassium ( outside):

When light enters the eye it first enters through your cornea‚ the transparent protective coating over your eye. Next it will pass through the pupil which is the small opening in the middle of your iris‚ or colored part of your eye. The muscles in the iris help to protect the eye by expanding and contacting based on the brightness of the light in your environment helping you see much clearer in bright and dim light. In side the pupil the light will then move through the lens which focuses the light

Which of the following are also found in the cell membrane: lipids‚ proteins‚ or carbohydrates? What is the role of steroids in a cell membrane? Cell membranes contain all three of the above groups‚ lipids are found abundantly in cell membranes‚ steroids are a type of lipids which helps with membrane fluidity by restricting the motion of the fatty acid tails.
