Within a cell, the energy released by electrons is often used to phosphorylate which of the following molecules? a. ATP b. ADP c. Pyruvate ions d. Oxygen e. NAD When 10,000 molecules of ATP are hydrolyzed to ADP and Pi in a test tube, about twice a...
6. The energy stored in ATP is used to drive various cellular processes, such as active transport of molecules across cell membranes. 存储在ATP中的能量用于驱动诸如细胞膜上的分子主动运输等各种细胞过程。 7. ATP is essential for the functioning of enzymes, which are protein molecules that catalyze...

ATP molecules are recycled after each reaction. Both exergonic and endergonic processes require energy from these molecules. The three phosphate groups in this ATP molecule are high energy bonds, which means they release a lot of energy when the bond breaks. This molecule provides energy for vari...
Probing the ATP hydrolysis cycle of the ABC multidrug transporter LmrA by pulsed EPR spectroscopy. Members of the ATP binding cassette (ABC) transporter superfamily translocate various types of molecules across the membrane at the expense of ATP. This re... UA Hellmich,S Lyubenova,E Kaltenborn,...
Cellular respiration is the process by which nutrients are oxidized to release energy. This energy is stored in the form of molecules that can be readily hydrolyzed to release the energy. Answer and Explanation: The correct option f...
are essential for osmoregulation, for sodium-coupled transport of a variety of organic and inorganic molecules, and for electrical excitability of nerve and muscle. This enzyme is composed of two subunits, a large catalytic subunit (alpha) and a smaller glycoprotein subunit (beta). The catalytic ...
Chemiosmotic phosphorylation is the process of converting ADP to ATP in the inner membranes of mitochondria. The electron transport chain, which is found on the walls of mitochondria, contains an estimated 10,000 enzyme chains that draw energy from food molecules or photosynthesis (the creation of ...
What molecule is the energy source for virtually all of the work done by the cell? What molecules are responsible for transporting high energy electrons to the electron transport chain during cellular respiration? Which produces the most energy in the form of ATP?
Any unstable system of potentially reactive molecules could potentially serve as a way of storing free energy, if the cell maintained their concentration far from the equilibrium point of the reaction. However, as is the case with most polymeric biomolecules, the breakdown of RNA, DNA, and ATP ...
