What do mitochondrial and thylakoid membranes ave in common?
Mitochondrial and thylakoid membranes are sites of electron transport chains. They both use ATP synthase proteins in ATP production.
What form do proteins need to be in to go through the electron transport chain?
Proteins need to be in the form of enzymes embedded in the inner mitochondrial membrane to participate in the electron transport chain. These enzymes facilitate the transfer of electrons from one molecule to another, generating a proton gradient used to produce ATP.
What kinds of proteins can be found in cell membranes?
There are two kinds of proteins in a cell membrane: peripheral PROTEINS OR trans membrane proteins. Cell membranes are able to perform various functions only because of different membrane protein functions. Most of the membrane proteins have alpha helix structure.
What helps electron-carrying molecules move along the membranes of mitochondria and chloroplasts?
In mitochondria, electron-carrying molecules are moved along the membranes by protein complexes that pump protons across the inner membrane, creating an electrochemical gradient. In chloroplasts, electron-carrying molecules are helped along by the thylakoid membrane's structure, which provides a platform for electron transport proteins to interact and facilitate the movement of electrons during photosynthesis.
Can proteins pass through transport proteins?
No the soluble proteins can not pass though the transporters on the membrane. Transport proteins are highly specific they only allow the transport of ions such as Na or K across the cell. But transport proteins such as Hemoglobin can carry oxygen or CO2 to all the tissues for respiration.

Are aquaporins transport proteins responsible for facilitating the movement of water across cell membranes?
Yes, aquaporins are transport proteins that facilitate the movement of water across cell membranes.
Where are transport proteins located?
Transport proteins are typically located in cell membranes, where they facilitate the movement of molecules across the membrane. These proteins can be found in both the plasma membrane of the cell and the membranes of intracellular organelles such as the mitochondria and endoplasmic reticulum.

What are the different kinds of proteins found in the human body and how do they function?
Proteins in the human body can be categorized into structural, enzymatic, regulatory, and transport proteins. Structural proteins provide support and shape to cells and tissues. Enzymatic proteins catalyze chemical reactions in the body. Regulatory proteins control various cellular processes. Transport proteins move molecules across cell membranes. Overall, proteins play crucial roles in maintaining the body's structure and function.
What do cell membranes look like and how do they function within a cell?
Cell membranes are composed of a double layer of phospholipid molecules with proteins embedded within them. These membranes have a fluid structure that allows them to regulate the passage of substances in and out of the cell. They function as a barrier to protect the cell and also play a role in cell communication and signaling. Additionally, cell membranes contain specialized proteins and channels that facilitate the transport of molecules across the membrane.
What are proteins found in cell membranes that transport large molecules?
carrier molecules
How do transport move substances across membranes?
Transport proteins change shape, much like a folding door
What do membrane proteins do in the context of cellular function and structure?
Membrane proteins play crucial roles in cellular function and structure by facilitating the transport of molecules across cell membranes, serving as receptors for signaling molecules, and helping to maintain the integrity and stability of the cell membrane.
Which group of iron-sulfur proteins in the electron transport chain accepts electrons from FADH2?
The iron-sulfur proteins in the electron transport chain that accept electrons from FADH2 are known as Complex II or succinate dehydrogenase.
