BIOD 171 Portage Learning Final Exam Review
1. True/False. A virus is considered a microorganism.: False, Viruses are no
living and as such are not considered microorganisms. Viruses can, however, b
classified as microbes, a more general term that includes microorganisms an
viruses.
2. What is the smallest biological unit of life?: A cell
3. What are the four main types of macromolecules found in cells?: Proteins,
Lipids, Nucleic Acids, Carbohydrates
4. Proteins are formed from various combinations of: Amino acids
5. There are how many known forms of amino acids: twenty
6. How many amino acids are classified as being essential amino acids?: Nin
7. Where can the two major types of nucleic acids be found in the cell?: DNA
RNA. Found in the nucleus.
8. What is the role of RNA?: RNA , found in the nucleus is capable of leaving
the nucleus. RNA is repsponsible for deciphering the hereditary information in DNA
and uses it to synthesize proteins.
9. What is the role of DNA?: DNA, found in the nucleus contains vast amount
of hereditary inforamtion, responible for inhereitable characteristic os living
organisms.
10. Complete the following RNA strand, and indicate how many bonds are
formed for each complementary pair:
3' GGUCAUCG 5'5' CC AGC 3': 3' GGUCAUCG 5'5' CCAGUAGC 3'There are 2
bonds formed between A and U, and 3 bonds between G and C.
11. The plasma membrane: Restricts movement of materials in and out of the cel
& Prevents essential nutrients from escaping
12. How many carbon atoms are present in glucose?: 6
13. True of False: The genetic material within a prokaryotic cell is containe
within a membrane-enclosed region.: False
Only eukaryotic cells contain its genetic material within a nucleus.

14. True or False: Prokaryotic cells can be subdivided into Bacteria an
Archaea.: True
15. True or False: Archaea is noted for its ability to survive under hars
conditions. Correct!: True
Archaea can often be found in harsh conditions such as high salt levels, high acid
conditions, high temperatures and even oxygen-poor conditions.
16. Which of the following microorganisms are considered to be Eukarya?
Select all that apply.: Animalia, Plantae, Fungi, Protista
17. Microorganisms classified as Plantae obtain most of their energy b
converting [answer1] energy into [answer2] energy.: 1. Light (sunlight) 2
chemical (sugars)
18 Which of the following are considered Protista? Select all that apply.: Algae
Amoeba
19. The function of the ribosome is: Protein synthesis
20. True or False: Protista retain a unicellular classification, as they are unabl
to form tissue layers.: True
21. Where are ribosomes located?: cytoplasm of prokaryotic cells and in the ER o
eukaryotic cells.
22. The combination of the cell membrane and the outer membrane is referre
to as the: Cell envelope
23. The function of the mitochondria is: To produce energy (ATP)
24. True or False. All multicellular microorganisms classified as Animalia ar
autotropic.: False
25. True or False: Metabolism is a controlled set of biochemical reactions tha
occur in living organisms in order to maintain life.: True
26. True or False: Enzymes slow down chemical reactions to conserve energy
False
