How do neutral solutes move across the plasma membrane? Can the polar molecules also move across it, in the same Why? If not, then how are these transport acorss the membrane?

Name the proteins that are involved in the transport of molecules across the membrane.

Go through the following statements (i) In human beings, the membrane of the erythrocyte has approximately 52 percent lipids and 40 percent proteins (ii) Lipids are arranged within the membrane with the hydrophobic tails towards the outer side and the polar head towards the inner side. (iii) As the polar molecules cannot pass through the non- polar lipid bilayer, they require a carrier protein of the membrane to facilitate their transport across the membrane (iv) The endomembrane system includes endoplasmic reticulum, Golgi complex, lysosomes and peroxisomes Find out the wrong peroxisomes :

In a passive transport across a membrane, when two protein molecules move in opposite directions, and are independent of each other, it is called…

The carrier - mediated cotransport in which a solute is actively transported across a membrane against the gradient of electrochemical potential by coupling the uphill transport of one solute to the downhill transport of another in an example of

Read the following four statements (A-D) (A) Both, photophosphorylation and oxidative phoshorylation involve up hill transport of protons across the membrane (B) In dicot stems, a new cambium originates from the cell of pericycle at the time of secondary growth (C ) Stamens in flowers of Gloriosa and Petunia are polyandrous (D)Symbiotic nitrogen-fixers occur in the free-living state also in soil How many of the above statements are right

How much work is done in moving 4 C across two point having pd. 10 v

Atoms of seven elements A, B, C, D, E, F, and Ghave different number of electron shells but have the same number of electrons in the outermost shells. How do the following properties vary as we move from A to G? (i) Metallic character (ii) Atomic radii (iii) Valency?

How does the electronegativity changes as we move from left to right across a period ?

A rectangular wire loop of sides 8 cm and 2 cm with a small cut is moving out of a region of uniform magnetic field of magnitude 0.3 T directed normal to the loop. What is the voltage developed across the cut if the velocity of the loop is 1 cm " "s^(-1) in a direction normal to the : (ii) shorter side of the loop ? For how long does the induced voltage last ?
