1D: Cellular Process and Transport

Multiple Choice

What is the Cell Membrane's structure?

• The cell membrane is structured as a phospholipid bilayer with embedded proteins.
• The cell membrane is a single layer of phospholipids without proteins.
• The cell membrane consists solely of cholesterol molecules.
• The cell membrane is a rigid structure made of cellulose.

Multiple Choice

How does the cell membrane help maintain homeostasis?

• The cell membrane acts as a storage unit for nutrients.
• The cell membrane generates energy for the cell.
• The cell membrane allows all substances to pass freely.
• The cell membrane helps maintain homeostasis by regulating the movement of substances in and out of the cell.

Multiple Choice

Active transport

• With the concentration gradient, requires energy

• Against the concentration gradient, no energy

• With the concentration gradient, no energy

• Against the concentration gradient, Requires energy

Multiple Choice

Passive transport

• Down the concentration gradient, Requires energy

• Up the concentration gradient, Requires energy

• Down the concentration gradient, no energy

• Up the concentration gradient, no energy

Multiple Select

What are the types of passive transport (Select three)

• Facilitated Diffusion

• Endocytosis

• Osmosis

• Simple Diffusion

Multiple Choice

Describe facilitated diffusion

• Facilitated diffusion requires energy to move substances across the membrane.
• Facilitated diffusion is the process of active transport using ATP.
• Facilitated diffusion occurs only in plant cells and not in animal cells.
• Facilitated diffusion move substances across a cell membrane with the help of transport proteins, without the use of energy.

Multiple Choice

Describe Simple Diffusion

• Simple diffusion is the passive movement of molecules from high to low concentration.
• Simple diffusion is a process that only occurs in living cells.
• Simple diffusion moves molecules from low to high concentration.
• Simple diffusion requires energy input to occur.
