Consider a cell that requires much more ribose5‑phosphate than NADPH. The cell needs ribose 5‑phosphate but has a relatively high concentration of NADPH and a low concentration of NADP+. These conditions may occur in rapidly dividing cells.

How many protons, electrons, and neutrons are in each of the following isotopes? a. zirconium-90 b. palladium-108 c. bromine-81 d. antimony-123

Choose an equation that represents an enzyme-catalyzed reaction. (a) enzyme + substrate → enzyme-substrate complex (b) enzyme + substrate ←−→ enzyme + products (c) enzyme + substrate ←−→ enzyme-substrate complex → enzyme + products (d) enzyme + substrate ←−→ enzyme-substrate complex → enzyme-substrate complex + products

Iwould appreciate if someone could me.
