C) Osmosis Which transport mechanisms are classified as passive mechanisms? A) Diffusion and osmosis B) Active transport and endocytosis C) Exocytosis and phagocytosis D) Pinocytosis and receptor-mediated endocytosis
A) Diffusion and osmosis What is the main difference between active transport and passive transport?
Active transport requires energy to move molecules against their concentration gradient, while passive transport does not require energy and moves molecules down their concentration gradient. Which of the following is not an example of passive transport? A) Diffusion B) Osmosis C) Facilitated diffusion D) Endocytosis
D) Endocytosis How is active transport different from facilitated diffusion?
Active transport requires energy to move molecules against their concentration gradient, while facilitated diffusion does not require energy and moves molecules down their concentration gradient. Which is a passive process? A) Active transport B) Endocytosis C) Diffusion D) Exocytosis
C) Diffusion Which of the following is a type of passive transport? A) Active transport B) Endocytosis C) Osmosis D) Exocytosis
C) Osmosis What are the two main types of transport?
The two main types of transport are passive transport and active transport. What is a difference between facilitated diffusion and active transport?
Facilitated diffusion does not require energy and moves molecules down their concentration gradient, while active transport requires energy to move molecules against their concentration gradient. How is active transport different from diffusion?
Active transport requires energy to move molecules against their concentration gradient, while diffusion does not require energy and moves molecules down their concentration gradient. What is the similarity between active transport and facilitated diffusion?
Both active transport and facilitated diffusion involve the use of transport proteins to move molecules across membranes. Which of the following is not an example of active transport? A) Sodium-potassium pump B) Endocytosis C) Diffusion D) Proton pump
C) Diffusion How is active transport different than simple diffusion and facilitated diffusion?
Active transport requires energy to move molecules against their concentration gradient, while simple diffusion and facilitated diffusion do not require energy and move molecules down their concentration gradient. Which of the following transport mechanisms is passive? A) Endocytosis B) Exocytosis C) Osmosis D) Active transport
C) Osmosis How do facilitated diffusion and active transport differ?
Facilitated diffusion does not require energy and moves molecules down their concentration gradient, while active transport requires energy to move molecules against their concentration gradient. Which of the following is a form of passive transport? A) Active transport B) Endocytosis C) Diffusion D) Exocytosis
C) Diffusion How are facilitated diffusion and active transport similar? How are they different?
Both use transport proteins to move molecules across membranes. Facilitated diffusion does not require energy and moves molecules down their concentration gradient, while active transport requires energy to move molecules against their concentration gradient. What are the two types of transport?
The two types of transport are passive transport and active transport. Which is an example of passive transport? A) Endocytosis B) Exocytosis C) Osmosis D) Active transport
C) Osmosis Which of the following is an example of passive transport across a membrane? A) Sodium-potassium pump B) Diffusion C) Endocytosis D) Proton pump
B) Diffusion Which two of the following are examples of passive transport? A) Diffusion B) Osmosis C) Active transport D) Endocytosis
A) Diffusion and B) Osmosis Which statement best describes passive transport?
Passive transport involves the movement of molecules across biological membranes without energy input, occurring from high to low concentration. Which of the following is a passive mechanism used to move materials into and out of the cell? A) Endocytosis B) Exocytosis C) Diffusion D) Active transport
C) Diffusion Which two transport mechanisms are considered to be passive? A) Diffusion and osmosis B) Active transport and endocytosis C) Exocytosis and phagocytosis D) Pinocytosis and receptor-mediated endocytosis
A) Diffusion and osmosis What type of transport is involved in this process?
The process described is passive transport, which involves the movement of molecules across biological membranes without energy input, occurring from high to low concentration. What is passive transport in biological membranes?
Passive transport is the movement of molecules across biological membranes from an area of high concentration to an area of low concentration without the use of energy. How does passive transport differ from active transport in terms of energy requirement?
Passive transport does not require energy, while active transport requires energy input, typically from ATP. In which direction do molecules move during active transport?
Molecules move from an area of low concentration to an area of high concentration during active transport. Why does active transport require energy?
Active transport requires energy because it moves molecules against their concentration gradient, from low to high concentration. What are membrane transport proteins?
Membrane transport proteins are proteins embedded in the cell membrane that facilitate the movement of molecules across the membrane. What is a uniporter?
A uniporter is a membrane transport protein that transports one type of molecule at a time in one direction across the membrane.
