Question

Answer as many as possible. Please and thank you

Here is what you better know: how exocytosis and endocytosis work what aquaporins are and how they function what osmosis is what hypotonic, hypertonic and isotonic mean and how they are used always in comparison what the three types of passive transport are, how they are similar and how they are different what active transport is what is required for active transport to occur and in which direction the solute molecules move via active transport what an enzyme is and how it functions how they speed up reactions what the graphs for exergonic and endergonic reactions show (can you label all the parts?) how exergonic and endergonic reactions are coupled what the energy of activation is what the graphs for enzyme mediated reactions look like (can you draw your own & label them .how enzymes function (catalyze chemical reactions)and what substrate is what the role of cofactors are how cofactors and coenzymes are similar and how they are different . what the recommended %'s of your calories should be from fats, carbohydrates and proteins what the energy value of the different macromolecules is per gram What the three main processes that ATP pays for

Answer 1

in Exocytosis materials are transported out of the cells via secretory vesicles.Endocytosis is cellular eating,cell’s plasma membrane surrounds a macromolecule or even an entire cell from the extracellular environment and buds off to form a food vacuole or phagosome.

Osmosis is  spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.

Enzymes are biological catalysts who speed up the reaction.It works by bringing down the activation energy for the reaction.

Activation energy : The minimum quantity of energy which the reacting species must possess in order to undergo a specified reaction.
