Exploring Cell Membrane Transport Mechanisms

What is the primary goal of the human body in terms of fluid and solute balance?

• To eliminate all solutes

• To decrease solute concentration

• To maintain a homeostatic environment

• To increase fluid intake

Which molecules can pass through the phospholipid bilayer via simple diffusion?

• Large charged molecules

• Glucose

• Tiny non-charged molecules

• Proteins

What is the main difference between simple diffusion and facilitated diffusion?

• Simple diffusion moves molecules from low to high concentration

• Simple diffusion requires energy, facilitated diffusion does not

• Facilitated diffusion uses special proteins, simple diffusion does not

• Facilitated diffusion only moves water

What type of transport moves molecules from a low concentration to a high concentration using energy?

• Osmosis

• Active transport

• Facilitated diffusion

• Simple diffusion

In osmosis, water moves through a semi-permeable membrane from:

• Low solute concentration to high solute concentration

• High water concentration to low water concentration

• Low water concentration to high water concentration

• High solute concentration to low solute concentration

What is the role of albumin in oncotic pressure?

• It breaks down solutes

• It pulls water into the capillary

• It pushes water out of the capillary

• It transports oxygen

What creates hydrostatic pressure in the circulatory system?

• Liver contractions

• Kidney function

• Heart contractions

• Lung expansion

What happens to water movement in a cell with high osmolarity inside?

• Water moves randomly

• No water movement

• Water moves into the cell

• Water moves out of the cell

How can healthcare professionals use osmosis to benefit patients?

• By reducing water intake

• By increasing physical activity

• By manipulating fluid solute concentrations

• By adjusting the patient's diet

What condition can result from low levels of albumin in the blood?

• Hypertension

• Hypoalbuminemia

• Hypokalemia

• Hyperglycemia
