Observations: Provide possible explanations to the following: Bubbles are coming out of the egg shell when soaked in vinegar The egg soaked in distilled water got bigger. The egg soaked in soda got bigger The egg soaked in corn syrup shrunk. The syrup turned watery.

Types of Transport Proteins The Plasma Membrane 9/12/2018 Types of Transport Proteins Channel proteins are embedded in the cell membrane & have a pore for materials to cross Carrier proteins can change shape to move material from one side of the membrane to the other copyright cmassengale G. Podgorski, Biol. 1010

Facilitated Diffusion The Plasma Membrane 9/12/2018 Facilitated Diffusion Molecules will randomly move through the pores in Channel Proteins. copyright cmassengale G. Podgorski, Biol. 1010

Facilitated Diffusion The Plasma Membrane 9/12/2018 Facilitated Diffusion Some Carrier proteins do not extend through the membrane. They bond and drag molecules through the lipid bilayer and release them on the opposite side. copyright cmassengale G. Podgorski, Biol. 1010

The Plasma Membrane 9/12/2018 Exocytosis The opposite of endocytosis is exocytosis. Large molecules that are manufactured in the cell are released through the cell membrane. Inside Cell Cell environment copyright cmassengale G. Podgorski, Biol. 1010
