Question

categorize each of the processes as passive transport or active transport.
process type of transport
sodium - potassium atpase pumps select choice
channel proteins select choice
diffusion select choice
exocytosis select choice
osmosis select choice
endocytosis select choice
carrier proteins select choice

Explanation:

• Sodium - potassium ATPase pumps use energy (ATP) to move ions against their concentration gradient, so it's active transport.
• Channel proteins allow substances to move down their concentration gradient without energy input, so it's passive transport.
• Diffusion is the movement of substances from high to low concentration without energy, so it's passive transport.
• Exocytosis is an energy - requiring process to release substances out of the cell, so it's active transport.
• Osmosis is the diffusion of water across a semi - permeable membrane from high to low water potential without energy, so it's passive transport.
• Endocytosis is an energy - consuming process to take substances into the cell, so it's active transport.
• Carrier proteins can be involved in both passive (facilitated diffusion) and active transport, but generally when not using energy to move substances down their gradient, it's passive transport.

Answer:

• Sodium - potassium ATPase pumps: Active transport
• Channel proteins: Passive transport
• Diffusion: Passive transport
• Exocytosis: Active transport
• Osmosis: Passive transport
• Endocytosis: Active transport
• Carrier proteins: Passive transport
