What type of protein is used to carry other molecules?
Carrier proteins are types of proteins used to carry other molecules, such as ions or small molecules, across cell membranes. These proteins can bind to specific molecules and transport them from one side of the membrane to the other. Examples include ion channels and transporters.
What are the types of carrier molecules for the ETC and where are they found?
The carrier molecules for the electron transport chain (ETC) are flavoproteins, iron-sulfur proteins, coenzyme Q, and cytochromes. These molecules are found embedded in the inner mitochondrial membrane where they shuttle electrons during the process of oxidative phosphorylation.
What is energy-carrying molecule called?
carrier molecule1. A molecule that plays a role in transporting electrons through the electron transport chain. Carrier molecules are usually proteins bound to a nonprotein group; they can undergo oxidation and reduction relatively easily, thus allowing electrons to flow through the system. There are four types of carrier: flavoproteins (e.g. FAD), cytochromes, iron-sulphur proteins (e.g. ferredoxin), and ubiquinone.2. A lipid-soluble molecule that can bind to lipid-insoluble molecules and transport them across membranes. Carrier molecules have specific sites that interact with the molecules they transport. Several different molecules may compete for transport by the same carrier. See transport protein.
Which of the following types of membrane proteins are responsible for facilitated diffusion?
Channel proteins and carrier proteins are responsible for facilitated diffusion. Channel proteins form hydrophilic channels that allow specific ions or molecules to pass through the membrane, while carrier proteins undergo conformational changes to transport molecules across the membrane.
What are the two types of possive transport?
The two types of passive transport are simple diffusion and facilitated diffusion. Simple diffusion involves the movement of molecules across a cell membrane without the need for a specific protein. Facilitated diffusion, on the other hand, requires the assistance of specific transport proteins to move molecules across the membrane.

What are the two types of transport across the cell membrane?
active transport and passive transport. active transport requires energy and able to transport molecules from low concentration side to higher concentration side. passive is just like a tube that connects innner side and outer side. it requires no energy but unable to do like active transport does

What are the four types transport mechanisms of drugs?
There are four types of transport mechanisms of drugs.1) Passive transfer includes A)Simple diffusion, means from higher concentration to lower concentration. B) Through Filtration, means through small pore in membrane. 2) Carrier mediated transport includes A) Active transport, in witch a carrier protein takes in a drug molecule with spending energy. B) Facilitated diffusion, by witch carrier protein molecule takes in the drug without spending energy and come back to take another drug molecule inside the cell.
What is the movement of molecules that requires energy?
No,the movement of molecules through diffusion does not use energy.Diffusion is just the movement of molecules from a region of higher concentration to a region of lower concentration.It is of two types-simple and facilitated;facilitated one is mediated by a carrier which is probably some protein.
What are the two types of possive transport?
The two types of passive transport are simple diffusion and facilitated diffusion. Simple diffusion involves the movement of molecules across a cell membrane without the need for a specific protein. Facilitated diffusion, on the other hand, requires the assistance of specific transport proteins to move molecules across the membrane.
Each is a type of RNA except?
Ribosome. Ribosome is a cellular organelle that is responsible for protein synthesis, while messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA) are different types of RNA molecules involved in the process of protein synthesis.
Name 2 types of passive transport?
Diffusion-the random movement of molecules from an area of higher concentration to an area of lower concentration.Osmosis-the diffusion of water across a semipermeable membrane.
