This chapter is about one thing...it's about how cells make ___.
Most life on earth acquires energy through ___________, followed by ________ _________.
photosynthesis, cellular respiration
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 ____.
CO2 and H20
What is the most efficient way to do catabolism?
Cellular respiration is a ________ breakdown
Fermentation is an ________ breakdown
The whole point of catabolism is to provide ________ for the manufacturing of ATP. ALL ABOUT MAKING ATP
Organic fuel is oxidized, what does that mean?
It means the removal of electrons
If something is oxidized, it's _______ its electrons.
Reduction is the ______ of electrons
If something is oxidized and loses its electrons, something else is reduced and _____ those electrons
What kind of bond does CH4 have?
non-polar covalent bond
What does non-polar covalent bond mean, in terms of electrons?
Electrons are all shared equally
What kind of bond does CO2 have?
What does polar covalent bond mean, in terms of electrons?
Electrons are not shared equally, oxygen is pulling on the electrons
Rule of thumb: watch the ________ !
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
Does the oxygen gain or lose hydrogens in the reaction?
It gained them, which means reduction
If you lose hydrogens, you're ________
If you gain hydrogens, you're ________
It's the _______ in methane that have the energy
In non-polar covalent bonds, electrons are ____ from the nucleus and have more energy
In polar covalent bonds, electrons are _____ to the nucleus and have less energy
What about electrons in glucose? Energy poor or energy rich?
Energy rich, non-polar covalent bonds
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!
This is the reaction that attaches an inorganic phosphate to ADP to make ATP. This is called _________.
When you join a phosphate to something, it's called __________.
ATP synthesis is _________.
What is the equation or "process" for cellular respiration?
C6H12O6 + 6O2 --> 6CO2 + 6 H20 + energy (ATP+heat)
What is the delta G for cellular respiration?
Delta G = -686 kcal/mole
