9. Describe the ping-pong mechanism using Lineweaver-Burk plot? (5pts)
Compare osmosis, simple diffusion, facilitated diffusion and active transport: A) describe their differences and B) explain when cells have to use each one.
Classify the phrases based on whether they describe or give an example of facilitated diffusion, active transport, or both. Facilitated diffusion Active transport Both Answer Bank movement to area of lower concentration movement across a membrane movement assisted by proteins glucose transport into muscle cell sodium ion transport out of cell requires energy
a) Solve for the optimal amount of food and ping-pong. (Assume that prices and income are such that some of both goods are consumed.) b) What is the marginal utility of ping-pong (at the optimal bundle)? Does Joseph enjoy ping-pong on the margin? c) Now suppose that Joseph undergoes surgery to get a prosthetic wrist. He once again achieves a high level of performance and is able to secure a contract playing ping-pong professionally in Albania. Is the price of...
How does facilitated diffusion differ from simple diffusion? Facilitated diffusion requires ATP Facilitated diffusion requires a solute-specific protein carrier Facilitated diffusion transports solute against its’ concentration gradient Which of the following is TRUE about primary active cell membrane transport? It is a form of transport that requires a protein “pump” It is a form of transport that transports ions and/or solute against their concentration gradient It is a transport mechanism that requires energy released from the splitting of ATP by...
•Differentiate between passive(simple) diffusion & passive facilitated diffusion. What is the role of proteins in facilitated diffusion? • what is the role of electrical gradient in membrane potential? • predict how membrane potential can change depending on the movement of positive charges in or out of the cell, starting with -70 mV
A Ping-Pong ball hangs from a string that is attached to the rear view mirror of a parked car. The driver side window is open, and the passenger side window is closed. A strong breeze blows along the driver side of the car. What happens to the Ping-Pong ball? Assume the breeze is laminar and that Bernoulli’s equation applies. A Ping-Pong ball hangs from a string that is attached to the rear view mirror of a parked car (see A...
A ping pong ball has a volume of 4.0 in3. Water has a weight density of 0.03613 lb/in3. What is the buoyant force on the ping pong ball when it is completely submerged in water?
The diameter of a brand of ping-pong balls is approximately normally distributed, with a mean of 1.31 inches and a standard deviation of 0.04 inch. A random sample of 4 ping-pong balls is selected. d. The probability is 54% that the sample mean will be between what two values, symmetrically distributed around the population mean? The lower bound is The upper bound is
A bowling ball collides elastically with a ping-pong ball, which is initially at rest. After the collision, the ping-pong ball’s speed is vp. What is the approximate final speed of the bowling ball? A. vp B. −vp C. 1 vp 2 D. zero
