Chapter 9, Problem 9TYU
Summary Introduction
To find: If the given figures represent active transport or passive transport.
Introduction: Cellular transport is the process of moving molecules and ions into and out of a cell. It requires specialized cellular structures and can involve either active transport, which requires energy, or passive transport, which happens without energy. Active transport moves molecules and ions against their concentration gradient, while passive transport moves molecules and ions along their concentration gradient.

Discuss how the structure of the SERCA Ca ion pump allows for the passage of Ca across themembrane. Make sure you detail the mechanism of transfer, where does the energy storycome in, timing of shape shifts, etc.
Describe the role of each of the membrane proteins shown in the picture below. Think about what is happening to the electrons and describe how energy is transformed as electrons move along the chain. Part of this involves the formation of the proton gradient. The other part is the explanation of the energetics of electron transport that you investigated above. In other words, the reason that electrons always flow from complex I to complex III to complex IV to oxygen.

Sodium-potassium ATPases are [passive/active] transporters that move sodium and potassium [with/against] their electrochemical gradients. In other words, potassium and sodium transport, without any coupled process, are [endergonic/exergonic] processes. These transporters are [primary active/facilitated/secondary active] transporters meaning that the transport process is coupled to [ATP hydrolysis/ion diffusion] to make the process spontaneous. P-type ATPases are [acid-base/covalent/nucleophilic] catalysts that become phosphorylated during the transport cycle. The sodium-potassium ATPase moves [3/2/1] cations out of the cell for every [1/2/3] cations it moves into the cell, polarizing the membrane such that the inside is [positive/negative] compared to the outside.

- In facilitated diffusion, what is the role of the transport protein? > View Available Hint(s) O Transport proteins allow solutes to move passively down their concentration gradient across the membrane. O Transport proteins provide the energy for diffusion of the solute. O Transport proteins provide a low-resistance channel for water molecules to cross the membrane. O Transport proteins provide a protein site for ATP hydrolysis, which facilitates the movement of a solute across a membrane. Transport proteins organize the phospholipids to allow the solute to cross the membrane.arrow_forwardK+ [Select] [Select] A Na+ Primary active transport is being shown by transporter [Select] which uses [Select] ATP [Select] B The transported molecules in this mechanism are being moved [Select] to move Glucose active transport is being shown by transporter [Select] which uses the gradient.

Phospholipid vesicles were made to contain beef heart mitochondrial ATP syn- thase and bacteriorhodopsin, a light driven proton pump isolated from Halobacterium holobium.

(1-5) As the H+ ions move through the ATP synthase it'll provide the power to make the ATP synthase to turn. As it turns, a phosphate group is added to an ADP, forming a proton gradient-energy as ATP. With the help of a channel protein called ATP synthase, these H* ions are transferred back to the matrix. The electrons are passed to another electron carrier called cytochrome C (cyt C), which carries the = electrons to enzyme complex IV. Here, the last batch of H* ions are pumped into the intermembrane space. Enzyme complexes I and Il then transport the electrons through ubiquinone (Q), a mobile electron carrier. Q is reduced to QH, in the process and delivers the electrons to enzyme complex III. As this happens, more H* ions are pumped into the intermembrane space. The NADH and FADH2 produced from the previous stages of cellular respiration bring electrons across the transport chain to initiate the oxidative phosphorylation.arrow_forwardComplex 2 EXTRACELLULAR SPACE glucose 3 Na plasma membrane K* electrochemica gradient Na electrochemical gradient glucose concentration gradient CYTOSOL ADP ATP Complex 1 Digoxin is a complex 1 inhibitor.

- 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.arrow_forwardTransportation by transporters and channels are similar in that they both can occur with passive transport but yet one (transport by transporters) sometimes requires energy in order to happen, does the use of energy provide something special to the cell?arrow_forward23.Summarize the steps that occur to set up secondary transport (co-transport) and during co-transport.

Three Na' ions inside the cell move OUT of the cell, across the Na*K* pump, from a low to a high concentration (AGAINST their concentration gradient). This requires the energy of ATP. This sets up the concentration gradient needed in the next step (the next step requires a low Nation concentration INSIDE the cell) 2. Nations in the interstitial fluid = extracellular fluid (fluid surrounding the cell) move INTO the cell, across a co-transport protein. The ions move from a high to a low concentration (DOWN their concentration gradient). This RELEASES energy. This energy is used in the next step. 3.
