What is formed at the end of the Electron Transport Chain by the combination of its reactant and hydrogen?
water
oxygen
carbon dioxide
glucose
The Electron Transport Chain is a series of chemical reactions in which energy is transferred to form a large amount of what molecule?

In which way are photosynthesis and cellular respiration similar?
Both processes destroy energy.
Both create energy.
Photosynthesis breaks down sugar while cellular respiration produces sugar.
Both processes transfer energy from one form to another.
What is the correct equation for cellular respiration?
oxygen + sugar -> carbon dioxide + water + Energy
carbon dioxide + sugar + Energy -> carbon dioxide + water
carbon dioxide + water -> oxygen + sugar + Energy
carbon dioxide + water + Energy -> oxygen + sugar
What is important about cellular respiration?
It produces energy from the sun.
It forms sugar.
It transforms sugar into a usable form of energy (ATP)
Only plants perform this process.
What's the chemical formula for glucose?
6C6H12O6
C12H6O12
C6H12O6
CHO
Which organ excretes (gets rid of) carbon dioxide?
Lungs
Liver
Heart
Kidney
One molecule needed for cellular respiration is
carbon dioxide
glucose
water
chlorophyll
Number of times we breathe in a minute is called
Breathing rate
Heart rate
pulse
exhalations
Which of the following would NOT be considered a constant in the body position activity? Remember constants are the factors that should be kept the same in an experiment.
Students were all the same approximate age.
All students performed the same body position examples.
Some students had coffee that morning while others did not.
Heart rate and breathing rates were collected for one minute.
Normal resting heart rate for adults
40-80 BPM
60-100 BPM
100-120 BPM
70-130 BPM
Which of the following information could be learned from the body position data activity?
Heart rate may be different depending on the person.
Breathing rates are higher in number per minute than heart rates.
Both breathing rates and heart rates can change because of body position.
The heart and lungs work together to give the body oxygen.
What are the 3 reactants of photosynthesis? The reactants are the things needed for photosynthesis to occur.
oxygen, glucose, sunlight
sunlight, oxygen, water
water, oxygen, carbon dioxide
carbon dioxide, sunlight, water
What are the 2 products of photosynthesis? The products are the things made in the process of photosynthesis.
water, sunlight
glucose, carbon dioxide
oxygen, glucose
sunlight, oxygen
What is the main purpose of photosynthesis?
To make food
To create energy
To release oxygen
To absorb sunlight
