(1) Does the magnitude(大小) of the free energy change for ATP hydrolysis increase or decrease as the pH increases from 5 to 6? Why? (6分)(2) A certain metabolic pathway can be diagramed asWhere A, B, C, and D are the intermediates(中间体), and X, Y, and Z are the enzymes...
ATP (ā′tē′pē′) Short foradenosine triphosphate.An organic compound, C10H16N5O13P3, that is composed of adenosine and three phosphate groups. It serves as a source of energy for many metabolic processes. ATP releases energy when it is broken down into ADP by hydrolysis during cell met...
Free Energy of ATP hydrolysis manipulates the cellular calcium signals In living cells, oscillation of the concentration of cytosolic Ca2+ is an important and pervasive signal for the intercellular and intracellular information conduction. To generate the oscillation, the hydrolysis of ATP is always need...
In the case of active transport or muscular contraction the free energy for transport or contraction is derived from the hydrolysis of ATP and the overall drive arises because the chemical potential of ATP is greater than that of its products (ADP and P) at physiological concentrations. But to...
ATP serves as the major energy source within the cell to drive a number of biological processes such as photosynthesis, muscle contraction, and the synthesis of proteins. It is broken down by hydrolysis to yield adenosine diphosphate (ADP), inorganic phosphorus, and energy. ADP can be further ...
We used phosphorus magnetic resonance spectroscopy to assess in vivo the brain cytosolic free magnesium concentration and the free energy released by the reaction of adenosine triphosphate (ATP) hydrolysis (螖 G ATPhyd), the latter being an index of the cell's bioenergetics condition. We studied ...
cellular respiration and energy production. Some of them participate in the process of oxidative phosphorylation, whereby the energy released by the oxidation of carbohydrates and fats is utilized for the synthesis of adenosine triphosphate (ATP) and thus made directly available for energy-requiring ...
which transports two Ca2+ions out of the cell for every ATP hydrolyzed. The ΔG°’ of ATP hydrolysis is enough to do transport only a single ion. Because, however, the ATP/ADP ratio is kept very high during active metabolic conditions, the concentration gradient of higher [Ca2+]...
