Hydrolitic properties

Hydrolitic enzymes

Hydrolitic substrates

7. The soluble inner portion of chloroplasts are called stroma.

True

False

8. Eukaryotic flagella are chemically different than bacterial flagella.

True

False

9. Which of these describes the ROUGH (ER) specifically?

Part of the cytomembrane system, is a continuous network of tubes surrounded by a single membrane

Contains ribosomes and functions mainly in transporting proteins to the plasma membrane for secretion or insertion.

Has no associated ribosomes and is involved with lipid biosynthesis, among other things

10. Match the transport process to the definition. The movement of water across a semi-permeable membrane along its concentration gradient.

Osmosis

Facillitated diffusion

Active transport

Simple diffusion

11. Match the transport process to the definition. Molecules are "pumped" from areas of lower concentration to areas of higher concentration. This requires a selective transport protein, one that can hydrolyze ATP for energy. This process requires energy in order for transportation to take place.

Osmosis

Facillitated diffusion

Active transport

Simple diffusion

12. Which of these describe the nucleus of a eukaryotic cell.

Contains the genetic material (DNA) in the form of long, linear chromosomes. "Control center" or "brain" of the cell.

Has a nuclear envelope consisting of two plasma membranes dotted with nuclear pores.

A visible nucleolus is the site of the production of ribosomal subunits

All of these

13. Match the transport process to the definition. The substance being transported is following its concentration gradient, but it is too large, too polar, or both to cross the membrane. In order for it to cross, a specific transmembrane transport protein will open in order to allow for diffusion to proceed without use of energy.

Osmosis

Facillitated diffusion

Active transport

Simple diffusion

14. A eukaryotic cell may possess which of these?

Peptidoglycan

Cillia

Endospores

15. The cell wall of this organism, is made up largely of cellulose. Which is it?

Algae

Protista

Animalia

16. Of the transport processes, which of these control the transportation of glucose (requires a carrier protein, no energy). .

Osmosis

Facillitated (passive) diffusion

Concentration of water is greater inside

18. Which of these describe the SMOOTH (ER) specifically?

Part of the cytomembrane system, is a continuous network of tubes surrounded by a single membrane

Contains ribosomes and functions mainly in transporting proteins to the plasma membrane for secretion or insertion.

Has no associated ribosomes and is involved with lipid biosynthesis, among other things

19. Is it true that animal cells and protozoa have a cell wall?

True

False

both these organisms have no cell wall

Explanation

both these organisms have no cell wall

20. Hypotonic is...

Concentration of water is greater outside

Concentration of water is the same inside/outside

Concentration of water is greater inside

22. Which organism is composed of a repeating chain of the polymer, NAG.

Plant Cells

Animal Cells

Fungal Cells

23. Of the transport processes, which of these control the transportation of the ions Na, and K (requires carrier protein and energy).

Osmosis

Facillitated (passive) diffusion

Simple Diffusion

Active Transport

24. Match the transport process to the definition. Things move along their concentration gradient from higher to lower concentration, these "things" have properties that allow them to move in and out of the cell as if there were no barrier. This describes

Osmosis

Facillitated diffusion

Active transport

Simple diffusion

25. Which of there structures are similar/resemble both a eukaryote and a prokaryote?

The plasma membrane

The glycocalyx

Chromosome

All of these

Only A and C

26. Which of these describes the Endoplasmic Reticulum specifically?

Part of the cytomembrane system, is a continuous network of tubes surrounded by a single membrane

Contains ribosomes and functions mainly in transporting proteins to the plasma membrane for secretion or insertion.

Has no associated ribosomes and is involved with lipid biosynthesis, among other things

27. What is a eukaryotic flagellum made from?

Protein tubulin

Protein flagellin

Flagellar filaments

28. Tay-Sachs disease is an example of what?

Deactivation of the mitochondria

Lysosomal storage, where materials build up in the lysosomes

29. If you're a protozoan, the lysosome is your "recycling center."

True

False

The lysosome is your 'stomach and intestines'

Explanation

The lysosome is your 'stomach and intestines'

30. Which of these does NOT describe the Mitochondira of a cell?

Contains its own ribosomes and one single DNA molecule

Functions in aerobic cellular respiration, are present within all eukaryotic cells
