To determine: The ratio of surface-area-to-volume if a cell is a perfect cube and has a length of 100 µm.
Introduction: Every organism present in the environment is composed of cell. Cells perform a number of important activities that help in the survival of an organism. These activities are known as cellular activities. The plasma membrane is the outermost layer of a cell that protects it from the external environment.
To determine: The ratio of surface-area-to-volume if a cell is a perfect cube and has a length of 200 µm.
Introduction: Movement of molecules takes place from inside to outside and vice-versa in the living cells. There are two types of movement, endocytosis, and exocytosis, which are adapted for the movement of molecules across the cell membrane.

- ✓ Details Draw a protein that is embedded in a membrane (a transmembrane protein), label the lipid bilayer and the protein. Identify the areas of the lipid bilayer that are hydrophobic and hydrophilic. Draw a membrane with two transporters: a proton pump transporter that uses ATP to generate a proton gradient, and a second transporter that moves glucose by secondary active transport (cartoon-like is ok). It will be important to show protons moving in the correct direction, and that the transporter that is powered by secondary active transport is logically related to the proton pump.arrow_forwarddrawing chemical structure of ATP. please draw in and label whats asked.

- 1.)What cross will result in half homozygous dominant offspring and half heterozygous offspring? 2.) What cross will result in all heterozygous offspring?arrow_forward1.Steroids like testosterone and estrogen are nonpolar and large (~18 carbons). Steroids diffuse through membranes without transporters. Compare and contrast the remaining substances and circle the three substances that can diffuse through a membrane the fastest, without a transporter. Put a square around the other substance that can also diffuse through a membrane (1000x slower but also without a transporter).
