Energy
The main energy trapping molecule is _____.
Chlorophyll
A green pigment that traps energy form sunlight is ______.
Chlorophyll
In glycolysis, _______ moloecules of ATP are used in the first step, and _____ molecules of ATP are produced in the second step.
Two
Four
Which equation best represents photosynthesis?
6co2 + 6h2o > c6h12o6 + 6o2
Leaves appear green because the green portion of the light that’s strikes them is _____.
Reflected
The energy in glucose cannot be released by _______.
Photosynthesis
Which is not a part of adenosine diphosphate?
Glucose
In which types of organisms does the process shown in figure 9-5 take place?
Both plants and animals
Compare and contrast the terms of photosynthesis and cellular respiration.
Photosynthesis and cellular respiration are the exact opposite but they and both used for plants.
What do you think would happen to a plants energy trapping ability if suddenly the only pigment it contained was chlorophyll? What’s your reasoning?
The plant would not function correctly or make food so it would die with no food.
Compare and contrast aerobic and anaerobic processes.
An aerobic process contains oxygen and an anaerobic process does not contain or use oxygen.
Predict what would happen if all the ATP production in living things suddenly ceased?
Every living thing would die due to lack of energy, oxygen, and carbon dioxide
Which of the following organisms do not have a cell wall?
Animals
All living things are made up of ____
Cells
What do electron microscopes use to focus and magnify an image?
Electron beam
Each of the following is a main idea Of the cell theory except ______.

If a cell contains a nucleus, it must be a ____________
Eukaryotic cell
A cells contents would be the same as its surrounds, were it not for _____.
Selective permeability
A plasma membrane is made up of a _____
Lipid bilayer
Which is not a way that figure 7-2 is a model of cellular theory?
Bricks are solid
If you run or ride a bicycle as fast as you can, your muscles may begin to feel weak and gave a burning sensation. Explain what is occurring that accounts for this muscle fatigue.
Oxygen/ATP is slowly running out, but will eventually pick up again
Maintaining body temperature, transmitting nerve impulses, movement if cilia, and bioluminescence are various activities of organisms. What requirements do these activities have in common? Why is ATP so important in each activity?
They all require oxygen. When they begin to lose ATP, everything will tighten up and won’t work properly.
