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.

help fill in these blanks in [] 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.
