• Draw a protein that is embedded in a membrane (a transmembrane protein), label the lipid bilayer and the protein. 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. ●

Test Your Understanding 7.In cotransport (indirect active transport) (a) a uniporter moves a solute across a membrane against its concentration gradient (b) the move of one solute down its concentration gradient provides energy for transport of some other solute up its concentration gradient (c) a channel protein moves ions by facilitated diffusion (d) osmosis powers the movement of ions against their concentration gradient (e) sodium is directly transported in one direction, and potassium is indirectly transported in the same direction

Please ASAP. Thanku. Which of the following can undergo simple diffusion through a phospholipid bilayer? K+ H2O CO2 Glucose
Test Your Understanding 6.Electrochemical gradients (a) power simple diffusion (b) are established by pinocytosis (c) are necessary for transport by aquaporins (d) are established by concentration gradients (e) are a result of both an electric charge difference and a concentration difference between the two sides of the membrane
MAKE CONNECTIONS In Concept 6.7, you learned thatanimal cells make an extracellular matrix (ECM). Describethe cellular pathway of synthesis and deposition of anECM glycoprotein.
MAKE CONNECTIONS Is the flow of ions through a ligand-gated channelan example of active or passive transport? (Review Concepts 7.3 and 7.4.)
Q.1. We are familiar with the semipermeable nature of bio-membrane, then what types of molecules would be able to pass through them and what types of molecule would be failed to pass?
Describe active transport across the plasma membrane marking note of concentration gradient Nd energy requirements
Q:1 : What kinds of molecules pass through a el membrane mostesh??
For fusion of a vesicle with its target membrane tooccur, the membranes have to be brought to within 1.5 nmso that the two bilayers can join (Figure Q13–1). Assum-ing that the relevant portions of the two membranes at thefusion site are circular regions 1.5 nm in diameter, calcu-late the number of water molecules that would remainbetween the membranes. (Water is 55.5 M and the volumeof a cylinder is πr2h.) Given that an average phospholipid occupies a membrane surface area of 0.2 nm2, how manyphospholipids would be present in each of the opposingmonolayers at the fusion site? Are there sufficient watermolecules to bind to the hydrophilic head groups of thisnumber of phospholipids? (It is estimated that 10–12 watermolecules are normally associated with each phospho-lipid head group at the exposed surface of a membrane.)
WHAT IF? Some membrane proteins diffuse faster in the plasma membrane when the cytoskeleton or the extracellular matrix is artificially removed than when cells are unperturbed. Explain why.
8. Which of the following ion transport functions must be carried out by a pump? a. transport of Na+ from the extracellular space to the cytosol b. transport of glucose from the extracellular space to the cytosol c. transport of K+ from the cytosol to the extracellular space d. transport of Na+ from the cytosol to the nucleus e. transport of Na+ from the cytosol to the extracellular space.
