Chloroplasts
Write the equation for cellular respiration.
C₆H₁₂O₆ + 6O₂ →→→ 6CO₂ + 6H₂O + energy
Which of the following is best shown by figure 4.2 below?
Electron transport chain
In which process is lactic acid formed when there's not enough oxygen present for cellular respiration to take place?
Fermentation
Which process allows glycolysis to continue without oxygen?
Fermentation
Compare the storage capacity of ATP and glucose. How does the cell use each of these molecules to store energy?
Glucose stores 90 times more energy than an ATP molecule. Glucose is used to store large amounts of energy for long periods. ATP makes energy as needed and stores it to be used within a few seconds of being made.
Before cellular respiration, glucose must be broken down by the process of...
Glycolysis
What is the name of the process that breaks glucose down into pyruvate that is used in cellular respiration?
Glycolysis
Which region of the spectrum is not absorbed well by chlorophyll?
Green
Organisms that cannot make their own food and must obtain energy from foods they eat are called...
Heterotrophs
Which organisms use alcoholic fermentation to allow fermentation to continue to produce ATP?
Yeasts
Which chemical equation best represents photosynthesis?
6CO₂ + 6H₂O →→→ C₆H₁₂O₆ + 6O₂
Which of the following directly provides the energy needed for cell functions?
A phosphate group is removed from ATP
A granum is...
A stack of thylakoids
Which molecules carry chemical energy that cells use for their functions?
ATP
List high energy molecules that transfer energy.
ATP and NADPH
Where in the chloroplast is chlorophyll found?
In the thylakoid
What is the name of the cycle represented by the circle in the diagram? Where does the carbon dioxide necessary for this process come from?
It is the Calvin Cycle; The carbon dioxide comes from the air around us
What does the zigzag arrow in the digram represent?
It represents energy from sunlight.
The water molecules labeled A in Figure 4.1 are going to the thylakoid to take part in which processes?
Light dependent reactions
The breakdown of which of the following provides the largest number of ATP per molecule?
Lipids
Photosynthesis is to chloroplasts as cellular respiration is to...

The aerobic process of cellular respiration takes place in the...
Mitochondria
The part of cellular respiration that needs oxygen takes place inside the...
Mitochondria
A student is collecting gas given off from a plant in sunlight of 27°C. The gas is probably...
Oxygen
When pyruvate is a reactant in cellular respiration it means that...
Oxygen is present
An electron transport chain that produces ATP is part of both cellular respiration and...
Photosynthesis
Plants cannot release energy from glucose using...
Photosynthesis
Write a simple title for the diagram above.
Photosynthesis
Which is the main function of the electrons shown in Figure 4.2?
Provides energy to pump hydrogen ions
Products of photosynthesis are...
Reactants of cellular respiration
W/hat are the 2 reactants and the 2 products in the process illustrated above?
Reactants: Carbon Dioxide and Water Products: Sugar (Glucose) and Oxygen
Chemosynthesis is a process through which some organisms use energy from chemicals in their environment to build sugars in the absence of...
Sunlight
Plants take in the sun's energy by absorbing...
Sunlight
People who suffer from a heart attack have an increased ratio of lactic acid to pyruvic acid in their hearts. What does this observation say about the availability of oxygen in the heart muscle of someone who has had a heart attack? How could you use this information to screen people who might be at risk for a heart attack?
The amount of oxygen in the heart muscle of someone who has had a heart attack is decreased. Finding lactic acid in the hear shows there was a lack of oxygen caused by a form of clot, because lactic acid only appears when there is an absence of oxygen. This information suggests to screen at risk heart attack patients by testing/measuring the levels of lactic acid in parts of the heart as indication for risk of a heart attack.
How will the scientist be able to tell whether the mouse is carrying out cellular respiration?
The phenolphthalein in the flask will turn from pink to clear.
What happens to the sugars in photosynthesis?
They can be used for cellular respiration
The stroma is the region outside the...
Thylakoids
Where in plant cells are the energy-absorbing molecules for photosynthesis located?
Thylakoids
Which of the following is an autotroph?
Tree
