SC DF ca's fill PDF Following is a diagram illustrating the mechanisms of transport across cell membrane. Which of the statements about cell membrane transport is NOT true? Outside Inside Diffusion (passive transport) A channel formed by an integral membrane protein Facilitated transport Active transport Energy O Diffusion (passive transport) across cell membrane requires integral membrane proteins. Cell membrane O The mechanisms of transport through cell membrane include passive, facilitated, and active transport. O Active transport across cell membrane is an energy-driven process. O In facilitated transport, substances flow in/out of the cells through channels. Search PD P acc PD uniz recor maste per

Video experiment #2 Selective Permeability – Dialysis. https://youtu.be/2CNGe3jMej0 1. A solution containing starch and fructose is sealed inside dialysis tubing, then immersed in a cup of water containing iodine (I2). Note – Iodine + starch --> dark purple complex Is dialysis tubing permeable to iodine? Explain using evidence from your experimental observations.   Is dialysis tubing permeable to fructose? Explain using evidence from your experimental observations.   Is dialysis tubing permeable to starch? Explain using evidence from your experimental observations.

I posted this qs before too, but the answer could not be seen and stated "Math Processing Error". Please Asap. Thank you.
