ATP Synthase | Definition, Function & Location - Study.com
2023年11月21日 · ATP synthase is an enzyme located in the mitochondria of animal cells, and it produces adenosine triphosphate (ATP). ATP is a high-energy molecule used in many biochemical reactions.
How fast does the rotor in ATP synthase spin?
2012年5月4日 · The rotation rates at various ATP concentrations obeyed the curve defined by a K m of ≈30 μM and a V max of ≈350 revolutions per second (21 000 revolutions per minute) at 37°C. Some reported values of very high ATPase activities would predictrapid rotations such as bovine mitochondrial F1 (≈310 rps) (37), yeast mitochondrial F1 (≈280 ...
Solved ATP synthase, shown in the image, uses the proton - Chegg
Question: ATP synthase, shown in the image, uses the proton (H+) gradient to drive ATP synthesis. Put the steps of ATP synthesis in order from proton transport to the synthesis of ATP. First step matrix F1 Intermembrane space Last step Answer Bank Protons from the intermembrane space bind to proton binding sites on c subunit Each 8 subunit ...
Solved The yield of ATP by the mitochondrial ATP synthase - Chegg
ADP and product, ATP The number of pumped out of the matrix by FADH, xidation has decreased by 2HTherefore, the calculation of ATP yield changes from 6/3= 2.0 to 4.5/3=1.5 for FADH Four move into the matrix for each ATP formed. ATP synthase utilizes three H ATP to help drive the rotation of they subunit, and one to protonate an aspartate ...
biochemistry - In which direction does ATP synthase rotate?
2017年3月28日 · As such, any ATP synthase is also an ATP hydrolase. When it synthesizes ATP, the γ subunit runs in clockwise direction when observed from the “bottom” (the side closest to the F 0 and the membrane, see Fig. 2). When it hydrolyzes ATP (e.g., under non-physiological laboratory conditions) it runs counter-clockwise as the reaction, as well as ...
cellular respiration - Do all prokaryotes have ATP synthases and an ...
2016年4月22日 · (It ferments a variety of plant mono- and poly-saccharides to acetone, butanol and ethanol — used to produce explosives in the First World War.) Although it has some enzymes of the TCA-cycle, it is unable to use the cycle oxidatively, and, like Clostridium perifringens, lacks the enzymes of the electron transport chain and an ATP synthase.
molecular biology - Are there any organisms that lack ATP …
2014年6月2日 · ATP synthase is used by cells to synthesise ATP from ADP using energy from a proton gradient. Depending on which sites I look at, this is either a universal feature of living cells, or it's "almost universal", used by the vast majority of organisms.
Is ATP Synthase a channel or an enzymatic protein?
2015年12月9日 · ATP synthase is an enzyme, a molecular motor, and an ion channel all wrapped together in one structure (Fig. 1). It is an enzyme, because it generates ATP. It is a molecular motor, because the central rotor part turns about 150 times every second during ATP synthesis (Source: MRC mitochondrial Biology Unit).
What preceded ATP synthase? - Biology Stack Exchange
There are metabolic processes in which ATP is synthesised without the involvement of ATP synthase. The best examples are, in fact, two steps in the glycolytic pathway, catalysed by phosphoglycerate kinase and pyruvate kinase. This is why, in the absence of any aerobic metabolism, many organisms (like yeast for example) can grow quite happily ...
Difference in ATP synthesis in mitochondria and chloroplast
2018年10月28日 · $\begingroup$ Does this mean that the ATP synthase works same in both mitochondria and chloroplast. But what I have read is that 1 NADPH in mitochondria is capable of sending 6 H+ ions in to the space between the two membranes of mitochondrial. And it obviously produces 3ATP , so 2H+ for one ATP. $\endgroup$ –
