B.4B Cellular Transport and Cellular Processes 🏖️

which statements best describe the difference between active transport and passive transport?

• 
• 
• 
• 

Which statement best describes the role of insulin and glucose-transport proteins in this process?

• They stimulate a response from white blood cells during glucose entry into the cell.

• They keep the plasma membrane flexible when glucose is removed from the blood.

• They help to maintain stable glucose levels both inside and outside the cell.

• They utilize the excess energy the cell produces to create more glucose.

Which type of movement across a cell's plasma requires energy supplied by ATP?

• passive transport

• simple diffusion

• active transport

• osmosis

Based on the graph, which process is occurring between minute 5 and minute 10?

• nuclei are building amino acids for energy storage

• ribosomes are building carbohydrates to increase energy output

• chloroplasts are using energy to produce oxygen

• mitochondria are using oxygen to produce ATP

Which statement describes the process of osmosis in an animal cell?

• Sugar molecules move across the plasma membrane until the cell has enough energy to grow in size and divide.

• Water molecules move accross the plasma membrane until solute concentrations are equal on both sides of the membrane.

• Ions move across the plasma membrane until the inside of the cell has a higher concentration of positive charges.

• Enzymes move across the plasma membrane until the cell has completed metabolism.

Type of transport across the cell membrane where small particles like ions are moved with the concentration gradient (from High to Low concentration)

No energy is spent by the cell.

• passive transport

• Protein mediated active transport

• active transport

• Bulk transport

Osmosis is the movement of

• water molecules from low to high concentration

• particles from low to high concentration

• water molecules from high to low concentration

• particles from high to low concentration

• Molecules are moved from high to low concentration

What is the diffusion of water through a selectively permeable membrane?

• active transport
• osmotic pressure
• facilitated diffusion
• osmosis
