during cellular respiration is most accurate?
A. The majority of the energy produced is lost to the environment as
B. The energy must be transferred across the cell membrane to be used.
C. The energy produced must be stored in specialized organelles within
D. The amount of energy produced is greater than the amount of
4. Shown here is an incomplete chemical equation for the reaction known
6CO2 + 6H2O + light energy → 6O2 + ____
Which of the following substances correctly completes the equation?
B. Carbon dioxide
5. Which of the following summarizes the flow of matter and energy in
A. Energy is consumed to rearrange carbon dioxide molecules into
glucose and oxygen.
B. Carbon and energy are required to transform sugar molecules into
C. Energy is released when sugar and oxygen are recombined to form
carbon dioxide and water.
D. As oxygen and carbon dioxide are used, energy and glucose are
6. Albumin is a protein produced in the liver of both pigs and humans.
Based on this information, what other similarity can we predict
between these two organisms? Both organisms–
A. have more complex DNA than organisms that do not produce
B. have DNA that codes for globulin, another protein found in the liver.
C. produce new sequences of DNA in the same region of their livers.
D. share a similar sequence in one section of their DNA that codes for
7. Which of the following observations would support the claim that DNA
determines the structure of proteins produced by cells?
A. Organisms that produce proteins have different lengths of DNA.
B. Similar DNA sequences are found in organisms that produce the
C. Both DNA and the production of proteins was observed in early life
D. DNA is found in the nucleus of all cells that produce proteins.
8. Huntington’s disease (HD) is a condition which results from the inability
to produce a certain protein. Which of the following is most likely the
cause of Huntington’s disease?
A. A structural problem within the nucleus
B. An increase in glucose in the blood
C. A decrease in the fat intake of their diet
D. A miscoding in the DNA sequence
9. Which of the following processes is directly responsible for growth in
A. The division of cells into two identical cells
B. The movement of water across a cell membrane
C. The production of reproductive cells called gametes
D. The exchange of the gases oxygen and carbon dioxide
10. DNA replication is an important part of cellular division because correct
A. ensures that identical and complete genetic information is passed
to both daughter cells.
B. produces mutations that usually are advantageous for the survival of
C. combines sperm and egg to form a zygote that will develop into a
D. communicates information about the cellular environment to
Photosynthesis takes energy from the sun and carbon dioxide to make sugar and oxygen
Energy moves because of attraction and repulsion of charges
DNA code makes proteins
Monomer: One, Polymer: chain of monomers
DNA replication leads to 2 daughter cells with identical DNA
