Part I – Introduction to Diffusion and Osmosis1. Define the terms diffusion, passive transport, active transport, and osmosis. In each of your definitions, describe the role of a concentration gradient. 2. Biological membranes are said to be selectively permeable (or semi-permeable). What does this term mean, and how does this affect the way that molecules are able to move through cellular membranes? 3. Which type of molecule is more likely to quickly pass through a cellular membrane via simple diffusion, polar or nonpolar? Why? (You may need to use information from your textbook and class discussions to answer this question.)

3. Please check if correct

2. Circle the correct bolded blue word. a. A substance that moves across a membrane "down" or "with" their concentration gradient is moving from the side with a higher / lower concentration of that substance to the side with a higher / lower concentration. This does / doesn't require energy input and is called active / passive transport. b. A substance moving "against" or "up" its concentration gradient is moving from the side with a higher / lower concentration of that substance to the side with a higher / lower concentration. This does / doesn't require energy input and is called active / passive transport. c. If the energy from the hydrolysis of ATP is directly used to pump the substance, the transport is called primary /secondary active transport. d. Ion-coupled transport is primary /secondary active transport and has two parts. First, the hydrolysis of ATP is used to power the creation of an ion concentration gradient. The ion is typically Na* or H*. Second, the energy stored in…

11:28 PM Fri Oct 9 * 29% O T of + : Oct 8, 2020 at 2:10 PM NAME DATE PERIOD Cell Membrane Discovery Big Idea: Cells move materials in and out of their environment through the cell membrane in order to maintain (balance) or (equal state). Composition of the Cell Membrane & Functions: The cell membrane is also called the membrane and is made of a phospholipid The phospholipids have a (water attracting or polar) head and two (water repelling or non-polar) The head of a phospholipid is made of an alcohol and phosphate group, while the tails are 2 chains of fatty acids. Phospholipids can move apart and allow water and other molecules to pass through into or out of the cell. This is known as simple because it does not require and the molecules are moving from areas of concentration to an area of concentration. 1. LABEL a phospholipid bilayer coloring the heads red and the tails blue. 2. LABEL the structure that is hydrophobic and hydrophilic. PHOSPHOLIPID molecule membrane Another type of…

The movement of molecules in and out of a cell is essential to its function. The cell membrane regulates this movement though processes such as diffusion, osmosis, active transport, etc. These activities on the next couple pages are designed to assess your understanding of these processes. Scenario #3 Semi-permeable membrane Охудen Carbon Dioxide Lungs I Blood stream After studying the image above, select the statement(s) that would explain what is likely to happen. Choose ALL that apply. O The carbon dioxide molecules will move into the lungs until equalibrium is reached. O All the carbon dioxide molecules will move into the lungs to be exhaled. O All the oxygen molecules will move from the lungs into the blood stream. O The semipermeable membrane will prevent the movement of either molecule. O The oxygen molecules will move into the blood stream until equalibrium is reached.

Hello need help with this question Unit is biochemistry, you could draw out the structure. Could you make sure it’s detailed and explained to your best of ability, I really appreciate it.

Please answer questions 1a, b, and c please.
