The power to do work is |
Energy |
|
List four forms that energy can take (not kinetic or potential) |
a. Light b. Heat c. Chemical Energy d. Concentration Gradient |
|
The Greenhouse Effect traps energy in Earth's atmosphere in the form of |
Heat |
|
The food we eat stores energy in the form of |
Chemical Energy |
|
The location on a molecule where energy is stored is the |
Molecular Bond |
|
ATP gives up one to become ADP. |
Phosphate Group |
|
help chemical reactions work, but are not used up in the process. |
Enzymes |
|
A molecule that takes electrons from another molecule is called an |
oxidizing agent. |
|
the particles which actually move from one molecule to another in energy transfer are the |
electron particles. |
|
When a molecule loses electrons to another molecule. This is called |
oxidation. |
|
When a molecule gains electrons from one another molecule. This is called |
reduction. |
|
The reason the ATP molecule has so much energy is because all the phosphate groups have a charge. |
negative |
|
Wite the short formula for cellular respiration: |
Glucose (C6H12O6)) + O2 + ADP --> H20 + CO2 + ATP |
|
The three main steps in a cellular respiration are |
1. glycolysis 2. Krebs cycle 3. Electron Transport Chain |
|
In glycolysis, one molecule of glucose becomes two molecules of |
Pyruvic Acid. |
|
In what chemical form is glucose when it enters the Krebs Cycle? |
Acetyl-CoA |
|
In cellular respiration, the main electron carrier is the molecule |
NADH. |
|
Most of the ATP in aerobic respiration is produced during |
Electron Transport Chain |
|
The last electron acceptor in the electron transport chain is |
oxygen. |
|
The organelle where most of aerobic respiration takes place is the |
mitochondria. |
|
At the end of aerobic respiration, the oxygen we breathe in ends up in a molecule of |
water. |
|
the carbon atoms in the carbon dioxide gas we breathe out come from molecules of |
glucose. |
|
Oxygen gets into our cells, and carbon dioxide gets out, by the process of |
diffusion. |
|
What enzyme, in the inner membrane of the mitochondria, adds energy to the energy molecule? |
ATP synthase |
|
In aerobic respiration, the word "aerobic" means that is used. |
oxygen |
|
Which step in cellular respiration takes place in the cytosol? |
Glycolysis |
|
Which step in cellular respiration takes place in the inner compartment of the mitochondria? |
Kreb Cycle |
|
Which step in cellular respiration takes place in the inner membrane of the mitochondrion? |
Electron Transport Chain |
|
The ATP synthase molecule is driven by a concentration of |
protons. |
|
In cellular respiration, how man ATP are made during: a. Glycolysis? b. Krebs cycle? Electron Transport Chain? |
a. 2 b. 2 c. 32 |
|
How many ATP are used to start glycolysis? |
2 |
|
How many ATP are produced with the energy carried by one NADH molecule? |
3 |
|
Write the short formula for photosynthesis: |
CO2 + H2O --> Glucose + O2 |
|
In photosynthesis, plants take in energy in the form of |
light energy. |
|
The pores in the leaf of a plant that open and close to let CO2 in are |
stomata. |
|
The organelle where photosynthesis takes place is the |
chloroplast. |
|
The pigment that absorbs light energy and gives up electrons is |
chlorophyll. |
|
Photosystem II and Photosystem I are reactions. |
light dependent |
|
The light-independent step of photosynthesis is the |
Calvin Cycle. |
|
The main electron carrier in photosynthesis is |
NADPH. |
|
The enzyme rubisco "normally" binds with |
CO2. |
|
They oxygen released in photosynthesis comes from |
water. |
|
Light dependent reactions take place within the membrane. |
thylakoid |
|
Photosystem II receives from water. |
