1

This chapter is about one thing...it's about how cells make ___.

ATP

2

Most life on earth acquires energy through ___________, followed by ________ _________.

photosynthesis, cellular respiration

3

Our energy comes from the sun. It is harnessed by plants. The chloroplast converts that light energy into _______ energy, in the form of organic molecules.
Photosynthesis requires some starting material, and that would be ___ and ____.

chemical
CO2 and H20

4

What is the most efficient way to do catabolism?

Respiration

5

Cellular respiration is a ________ breakdown

complete

6

Fermentation is an ________ breakdown

incomplete

7

The whole point of catabolism is to provide ________ for the manufacturing of ATP. ALL ABOUT MAKING ATP

energy

8

Organic fuel is oxidized, what does that mean?

It means the removal of electrons

9

If something is oxidized, it's _______ its electrons.

losing

10

Reduction is the ______ of electrons

gain

11

If something is oxidized and loses its electrons, something else is reduced and _____ those electrons

gains

12

What kind of bond does CH4 have?

non-polar covalent bond

13

What does non-polar covalent bond mean, in terms of electrons?

Electrons are all shared equally

14

What kind of bond does CO2 have?

polar-covalent bond

15

What does polar covalent bond mean, in terms of electrons?

Electrons are not shared equally, oxygen is pulling on the electrons

16

Rule of thumb: watch the ________ !

HYDROGENS!

17

Electrons are transferred along with protons...what is a proton? A hydrogen atom. So if we're transferring protons, we're transferring hydrogens. Does Carbon gain or lose hydrogen's in this reaction?

It lost all of them

18

Does the oxygen gain or lose hydrogens in the reaction?

It gained them, which means reduction

19

If you lose hydrogens, you're ________
If you gain hydrogens, you're ________

oxidized
reduced

20

It's the _______ in methane that have the energy

electrons

21

In non-polar covalent bonds, electrons are ____ from the nucleus and have more energy

far

22

In polar covalent bonds, electrons are _____ to the nucleus and have less energy

close

23

What about electrons in glucose? Energy poor or energy rich?

Energy rich, non-polar covalent bonds

24

Glucose and fats are biologicals fuels...we consume them and drain them of their energy...BY WHAT?

OXIDATION. It's the electrons that have the energy, we're going to oxidize the heck out of them, get all those electrons!

25

This is the reaction that attaches an inorganic phosphate to ADP to make ATP. This is called _________.

phosphorylation

26

When you join a phosphate to something, it's called __________.

phosphorylation

27

ATP synthesis is _________.

Endergonic

28

What is the equation or "process" for cellular respiration?

C6H12O6 + 6O2 --> 6CO2 + 6 H20 + energy (ATP+heat)

29

What is the delta G for cellular respiration?

Delta G = -686 kcal/mole

30

How much energy is released when glucose is catabolized?

-686 kcal/mole
