Two test tubes, A and B, were set up as shown in the diagram below. Bromothymol blue, which turns from blue to yellow in the presence of carbon dioxide, was added to the water at the bottom of each tube before the tubes were sealed. The tubes were maintained at the temperature shown for six days. (Average room temperature is 20 degrees Celsius).

Write a CER response to identify the life process responsible for the change in tube A.

Look at the figure. All of the following are parts of an ADP molecule EXCEPT
Structure B
Structure A
Structure D
Structure C
What are the three parts of an ATP molecule?
stroma, grana, and chlorophyll
adenine, thylakoid, and a phosphate group
adenine, ribose, and three phosphate groups
NADH, NADPH, and FADH2
Which part of an ATP molecule provides energy for life processes?
chemical bonds
carbon atoms
oxygen atoms
inorganic nitrogen
Which statement BEST describes the relationship between adenosine diphosphate (ADP) and adenosine triphosphate (ATP)?
With an input of energy, ADP combines with a phosphate group to become ATP.
With an input of energy, ADP rearranges to become ATP.
Without any energy change, ADP rearranges to become ATP.
With a release of energy, ADP combines with a phosphate group to become ATP.
The diagram shows the molecular structure of adenosine triphosphate (ATP). Which of these events occurs during the normal function of ATP in the cell?
chemical bond forms between the adenine unit and the third phosphate group.
The chemical bond breaks between the adenine and ribose units.
The chemical bond breaks between the second and third phosphate groups.
The chemical bond breaks between the ribose unit and the first phosphate group.
Vernon is using the diagram shown below to develop a model of photosynthesis. The letters A, B, and C each represent a reactant or product of the process.


Should water (H2O) be included in the model as a reactant or product? If so, how should it be included?
Yes, as product B.
Yes, as product C.
Yes, as reactant A.
No, it should not be included.
Which equation best describes photosynthesis?
Energy, water, and chlorophyll yield carbon dioxide and oxygen.
Carbohydrates and carbon dioxide yield energy and oxygen.
Carbon dioxide, water, and energy yield carbohydrates and oxygen.
Water and energy yield carbohydrates and carbon dioxide.
One immediate cause of a decrease in the rate of photosynthesis is a reduction in the availability of
oxygen
hydrogen
carbon monoxide
carbon dioxide
The organelle(s) involved in photosynthesis is/are
vacuoles
chloroplasts and vacuoles
chloroplasts
mitochondria
Some sea slugs store chloroplasts obtained from algae they have ingested. The chloroplasts continue to carry out photosynthesis within the slugs. What advantage would this activity be to these sea slugs?
The chloroplasts provide the slugs with camouflage that protects them from UV radiation
The slugs with chloroplasts can synthesize some of their own food
The slugs with chloroplasts no longer need to carry out respiration
The chloroplasts contain enzymes that allow the slugs to digest starch.
What is the correct equation for cellular respiration?
6CO2 + 6H2O + Energy --> 6O2 + C6H12O6
6O2 + C6H12O6 + Energy --> 6CO2 + 6H2O
6CO2 + 6H2O + Energy --> 6O2 + C6H12O6
6O2 + C6H12O6 --> 6CO2 + 6H2O + Energy
ATP is a compound that is synthesized when
energy stored in nitrogen is released, forming amino acids
chemical bonds between carbon atoms are formed during photosynthesis
digestive enzymes break amino acids into smaller parts
energy stored in chemical bonds is released during cellular respiration
Which statement regarding respiration is correct?
fungi and monerans carry out aerobic respiration only
all living organisms carry out some form of respiration
all autotrophs and heterotrophs require glucose and carbon dioxide for respiration
respiration in autotrophic organisms occurs only during the day
A weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take in enough oxygen to make very much ATP, he begins to get fatigue in his muscles. Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?
The cells will never run out of oxygen if the weightlifter is breathing.
As the cells run out of oxygen, they die off gradually and the weightlifter’s muscles have fewer contracting muscle cells.
As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of ATP in the absence of oxygen.
As the cells run out of oxygen, they will continue to make the same amount of ATP, since oxygen is not required to make ATP.
Which statement describes how photosynthesis and cellular respiration are interrelated?
Photosynthesis releases the energy that is stored during the process of cellular respiration.
Glucose is used during cellular respiration to produce food that is broken down during photosynthesis.
Oxygen is produced during cellular respiration and stored during photosynthesis.
Carbon dioxide and water released by cellular respiration are used in photosynthesis.
Although animals do not perform photosynthesis, their food supply depends on the sugars that photosynthesis produces. What is the other significant benefit to animals that photosynthesis provides?
adding carbon dioxide to the atmosphere
generating ATP and NADPH
adding oxygen to the atmosphere
removing water from the environment
Which of the following best describes a distinct difference between photosynthesis and cellular respiration?
Cellular respiration takes place in the chloroplasts; photosynthesis takes place in the mitochondria.
The process of cellular respiration releases energy; the process of photosynthesis stores energy.
The process of cellular respiration involves glucose; the process of photosynthesis does not.
The waste product of cellular respiration is oxygen; the waste product of photosynthesis is carbon dioxide.
Which set of terms best identifies the letters in the diagram below?
