What is one difference between eukaryotic cells & prokaryotic cells?

• Eukaryotic cells replicate faster

• Prokaryotic Cells hace Cell Membranes

• Eukaryotic Cells are more complex than Prokaryotic cells

• Prokaryotic cells are larger than Eukaryotic cells

Proteins can have different functions in an organism. What type of protein will help a cell maintain its shape?

• Transport Protein

• Enzyme Protein

• Structural Protein

• Messenger Protein

Enzymes catalyze reactions. If an enzyme is denatured, will a reaction still occur?

• YES the reaction will still take place

• NO, when an enzyme is denatured, it no longer has the ability to speed up a reaction

Cell transport happens along the cell membrane. If moving a substance occurs AGAINST THE CONCENTRATION GRADIENT, will it require energy (ATP)?

• YES, it will require ATP in order to go from an area of LOW concentration to an area of HIGH concentration.

• No, it does NOT require ATP to go from LOW to HIGH areas of concentration.

• Yes & No, enery is not a factor when moving molecules in & out of a cell.

• It uses superpowers to fly across the cell membrane

Why are lipids important to the structure & function of a cell?

• Store energy

• hydrophobic & hydrophyllic areas form a bilayer of protection

• Lipids control the rate of reaction

• Lipids can be a chemical messenger for the cell

• No

• Photosynthesis

• Cellular Respiration

• Urinating
