Review For Mock

When comparing Lipids and Carbohydrates, there is one thing they have in common. What is it?

• They both are Sugars

• They both are Fats

• They both are Monosacharides

• They both store Energy

There are two types of cells.

Those like plants and animals that are complex and have all organelles (Eukaryotic).

and those that only have ribosomes and DNA floating around (Prokaryotic)

What are two ways you could Identify a Prokaryotic Cell?

• There is NO nucleus in the cell

• There is only DNA and Ribosomes in the cell

• The cell has all the organelles

• The cell has a nucleus

If a cell has 7.1% Salt inside of it,

Which of these 4 solutions would cause the cell to get bigger?

5.4% Salt Solution

7.1% Salt Solution

9.3% Salt Solution

11.2% Salt Solution

• 5.4% Salt Solution because Water will move into the cell

• 7.1% Salt Solution because Water will move both in and out of the cell

• 9.3% Salt Solution because Water will leave the cell

• 11.2% Salt Solution because Water will leave the cell

Which two components would be found in both a Virus and a Prokaryotic Cell?

• Nucleic Acid (DNA/RNA) and Carbohydrates (sugar)

• Carbohydrates (sugar) and Lipids (fat)

• Lipids (fat) and Proteins

• Proteins and Nucleic Acids (DNA/RNA)

Which of these cells are most likely to result in cancerous cells?

• Cells undergoing Slower rates of Mitosis

• Cells with Few or No Mutations

• Cells not responding to Checkpoints in the cell cycle

• Cells with decreased rates of protein synthesis

Which statement best describes how genes are expressed in an organism?

• Genes are always off even when resources are available.

• Genes are turned on and off in response to environment.

• Genes are continuously turned on and off at random intervals of time.

• Genes are on until all the genes have been simultaneously expressed.

Which statement best describes how enzymes affect the speed of metabolic reactions?

• Enzymes increase the concentration of reactants, which increases the speed of the reaction.

• Enzymes decrease the energy needed to start a reaction, which increases the speed of the reaction.

• Enzymes replace the reactants in a chemical reaction which decreases the speed of the reaction.

• Enzymes prevent products from being converted back into reactants, whihc decreases the speed of the reaction.

Bacteriophage (virus) uses the lysogenic cycle to replicate itself. Which of the following best represents this cycle.

• Virus DNA/RNA is injected into the cell and integrates with the Cell's DNA/RNA. It then stays dormant until it is triggered into the Lytic cycle and kills the cell.

• Virus DNA/RNA is injected into the cell and makes it make copies of it until it explodes

• Virus DNA/RNA is injected into the cell and makes it explode instantly

• Virus DNA/RNA is injected into the cell and nothing ever happens to the cell or virus DNA/RNA.

If a:

Dried pea = ribosomes

Shelled peanuts = Mitochondria

Uncooked noodles = DNA/RNA

Shoestrings = Cell membrane

Which material would be used in a Eukaryotic cell (animal and plant),

but NOT in a Prokaryotic cell (bacteria).

• dried peas (ribosomes)

• shelled peanuts (mitochondria)

• uncooked noodles (cell membrane)

• shoestrings (cell membrane)

Which molecules are building blocks of DNA?

• Proteins

• Fatty Acids

• Nucleotides

• Chromosomes
