Why do cells need carrier proteins that transport glucose? Why is succinate important in the Krebs cycle? Why do germinating peas undergo cell respiration? The citric acid cycle does not require oxygen, however, it does not operate under anaerobic conditions. Explain why this is the case. ...
Which of the following processes causes most of the carbon dioxide from the blood to move into the alveoli? A. Conversion of carbon dioxide. B. Active transport using energy. C. Diffusion down concentration gradient. D. Passive transport using carrier pro ...
Movement of the cell against a concentration gradient is called: A) active transport B) diffusion C) osmosis D) passive transport Explain why the movement of a solute across a membrane by carrier proteins is subject to "saturation kinetics," and has a characteristic Tr...
Active transport of materials is rapid and usually occurs against the concentration gradient involving carrier proteins and energy in the form of ATP.

Facilitated diffusion is the process of molecules moving from a high to low concentration using a channel protein. Facilitated diffusion is based on movement due to a concentration gradient and does not actively use energy. Answer and Explanation: ...

(CAMK). It plays a central role in regulation of cell shape and polarity during differentiation, chromosome partition in mitosis, and intracellular transport by acting on microtubule-associated proteins (MAPs), including MAP2, MAP4 and tau [86,87]. It is predominantly expressed in the brain. ...
ABC transporters are powered by their NBDs which use the energy of ATP binding and hydrolysis to drive the alternating access of the substrate-binding site located in the TMDs. Reciprocally, the ATPase activity of ABC proteins is generally stimulated in the presence of substrates, although the deg...
What molecules require the use of carrier proteins? What are the viral proteins connected to the surface of the monocyte? What is the directionality of the macromolecules, carbohydrates, proteins, and lipids? What is a molecular chaperone? A. A protein that binds to...
What functions do carrier proteins perform in active transport? How are the proteins used for active transport different from those used for facilitated diffusion? How do proteins produce cellular membrane curvature? Describe how a cell produces and releases proteins. How many Golgi bodies are in ...
