C) Formation of NADPH
D) Calvin Cycle
What is the Calvin Cycle?
Formed by strands of transmembrane proteins that stitch adjacent plasma membranes together, creating a watertight, impermeable seal.
What are tight junctions?
The role of a secondary messenger in cell signaling.
What is relaying the signal received at the cell surface receptor?
A spontaneous chemical reaction that releases free energy into the system.
What is Exergonic?
The movement of hydrogen ions (protons) across a semipermeable membrane down their electrochemical gradient, which powers the enzyme ATP synthase to produce ATP.

E) Photolysis
What is Reduction of CO2 to sugars?
Considered the largest structure of cytoskeleton filaments and, together with other filaments, gives the cell shape and keeps the organelles in place.
What is a microtubule?
Category of cell signaling in which the cell that releases the signal also carries the receptor for it.
