With a Sodium/Potassium pump, Sodium ions move from the cytoplasm to outside the cell. (TRUE/FALSE)
Any process/reaction that releases FREE energy is _________ (Delta G is negative).
As the cell grows, the membrane expands. This is due in part to (endocytosis/exocytosis).
Converting sucrose to glucose would normally take years, but the _______ enzyme speeds up the reaction immensely.
(First/Second) Law of Thermodynamics: Entropy increases with each chemical reaction; heat is produced.
__________ energy is an investment of energy required to start a reaction.

QuestionAnswer
The sucrose/H+ cotransporter is considered (active/passive) transport.
Energy available to do work.
