False, a lipid bilayer is a MOSTLY apolar cell structure,which means polar molecules can't easily go through it
In the start of the light cycle, light-dependent reactions harness energy from the sun in order to create chemical bonds. These bonds are known as ATP and NADPH. These are the molecules that carry energy which are made in the stroma. The stroma is where the Calvin cycle takes place.
The activity of some enzymes requires vitamins. This is because vitamin derivatives contribute to the biochemical mechanisms of these enzymes. These vitamin derivatives belong to a class of molecules known as cofactors, which are organic molecules (called coenzymes) or metallic ions, that assist in the catalytic activity of an enzyme.
C applies as the kidney must excrete salt in order to get rid of excess water. (Water chases salt) if there is too much salt in the body the urine will be much more concentrated then if the body had too much water. Glucose may kbly be excreted if there are problems with the kidney- some diabetics pee out glucose. D applies to some degree- salt will still be excreted but in very dilute amounts- as the water must chase something in order to be excreted.
