Activators
Inhibitors

4

The end product of metabolic pathway acts as?

an inhibitor

5

What do pesticides do?

8

What kind of pathway does photosynthesis have?

anabolic/endergonic

9

Cellular respiration & photosynthesis both manage energy by?

electron transfer: Redox Rxn's
using coenzymes

10

What are Redox Reactions?

great energy (electron) conveyors
mvmt of electrons by electronegative molecules

11

What is oxidation?

loss of electrons and hydrogen ions

12

What is reduction?

gain of electrons and hydrogen ions

13

How do a series of Redox Rxn's manage energy release?

by stepping down electron transfer: falling

14

What happens in redox reactions in cellular respiration?

enzymes transfer the electrons/ H+'s to intermediate electron carriers
