Lab 1 Diffusion‚ Osmosis‚ and Water Potential of Glucose Problem: What effects will glucose have on diffusion‚ osmosis‚ and water potential? Background: All living things have certain requirements they must satisfy in order to remain alive. These include exchanging gases (usually CO2 and O2)‚ taking in water‚ minerals‚ and food‚ and eliminating wastes. These tasks ultimately occur at the cellular level‚ and require that molecules move through the membrane that surrounds the cell. There

just a chain of ami. tacids makes up the primary structure. The secondary structure is formed by hydrogen bonds joining the chains in certain places to make an alpha helix or a beta sheet. The tertiary structure is formed by even more folding and joining of the chains to make a globular mass or fibrous mass. An example of this would be a carrier protein. Proteins are needed for many things they are needed in our diet for growth and repair of cells‚ enzymes and hormones in the body are used for the

potential difference in voltaic cell. Aim: To investigate the effect of concentration of electrolyte of the potential difference in voltaic cell. Introduction: Chemical reactions involving the transfer of electrons from one reactant to another are called oxidation-reduction reactions or redox reactions. In a redox reaction‚ two half-reactions occur; one reactant gives up electrons (undergoes oxidation) and another reactant gains electrons (undergoes reduction). Voltaic cell is a device in which a

Cell Biology Oct.3/14 Cell Cycle part 3: Apoptosis 2 Main ways cells will die: apoptosis is regulated‚ nacrosis is an “explosion” Apoptosis Part of controling number of cells. Importance in balance.“Programmed cell death” – important because if the cell isn’t intact you don’t want cell to divide and keep mutations going‚ to avoid inflammatory response (caused by cells that exploded/necrosis).. ect. Necrosis is triggered by something unplanned‚ leading to decrease ATP‚ pumps‚ atpase activity

Differentiating Between Prokaryotic and Eukaryotic Cells‚ Distinguish Among Plant‚ Animal‚ and Protist Cells‚ and Identifying the Organelles that are Evident in Them Introduction There are two different types of cells‚ prokaryotes and eukaryotes. Prokaryotes‚ such as bacteria‚ lack a nuclear membrane and other membrane bound organelles. Their genetic material consists of a single molecule of singular DNA. Eukaryotes‚ such as plant and animal cells‚ have a nuclear membrane and other membrane bound

These differences are perhaps most highlighted in the medical field where stereochemistry of a molecule can be the difference between having a medically active‚ effective drug and a toxic‚ potentially

In a flowering plant‚ the water travels from the soil‚ then to the root hairs‚ next to the xylem‚ then into the stomata‚ to the mesophyll cells‚ next to the stoma‚ then finally into the atmosphere. Osmosis is the diffusion of water through semipermeable membranes. Transpiration is the evaporation of water from the leaf. Cohesion is when water molecules stick together. Adhesion is when water
