ATP is formed during phosphorylation, when A. a molecule gains a phosphate groupB. a molecule synthesizes a phosphate C. molecules become more stableD. molecules are passed to enzymesE. ADP is produced from ATP
is energy is released when ATP loses a phosphate group true about ATP and ADP
ATP works by A) donating energy B) none of these answers is correct C) donating two negative charges of the hydrolyzed phosphate D) adding ATP to other molecules, such as proteins
We have described the molecule ATP as the body’s energystorehouse. What do we mean by this designation? Howdoes ATP actually store energy and provide it to the bodyas needed?
Cells utilize the energy ot AlP to do usetul work, such as power muscle contractions. During cellular activities like muscle contractions, ATP is converted into ADP and a phosphate group. What is happening to energy in this process of conversion? A:Energy is being stored. B:Energy is being released. C:Energy is being destroyed. D:Energy is being created.
Which of these statements about ATP is true?a.The bond joining ADP and the third phosphate is a high-energy bond.b.The formation of ATP is coupled to energy-liberating reactions.c.The conversion of ATP to ADP and Pi provides energy for biosynthesis, cell movement, and other cellular processes that require energy.d.ATP is the “universal energy carrier” of cells.e. .All of these are true.
Energy is released from an ATP molecule for cellular processes when it___ A. Has a phosphate group removed B. Stores an extra phosphate C. Converts a phosphate group to ADP D. Produces a sugar molecule
Which of the following is associated with the H+ proton? a. Acts as a buffer against changes to muscle pH b. Accumulation impairs calcium handling by the sarcoplasmic reticulum (SR) c. Necessary molecule for the re-synthesis of ATP within the mitochondria d. All of the above e. Both B and C are correct
A 75 kg person doing light work requires about 3000 kcal of food energy perday, 40% of which is actually used by the body’s cells. (The other 60% is lostas heat and in waste products.) Before being used by the cells, effectively allof this energy is stored in ATP, which is then cleaved into ADP and PO3−2 , with the release of 12.5 kcal per mole of ATP.(a) How many moles of ATP are turned over per day in this fashion? Whatmass of ATP does this correspond to? (The molecular weight of ATP is507 g/mol.)(b) The body actually contains approximately 5 g ATP. Estimate the averagerecycle time for an ATP molecule. You see that it is much more efficientto reuse ADP rather than to synthesize it de novo (from scratch).
A molecule that donates electrons becomes _________, and the one that accepts the electrons becomes ________ . a. reduced; oxidized c. oxidized; reduced b. ionic; electrified d. electrified; ionic
Energy is stored long-term in the bonds of _____ and used short-term to perform work from a(n)_____molecule. a. ATP : glucose b. an anabolic molecule : catabolic molecule c. glucose: ATP d. a catabolic molecule : anabolic molecule
Which one of the following statement is CORRECT for ATP? Select one: a. Divalent cation C12- stabilize ATP and blocks the driving force for association and make ATP unstable b. In pure water ATP Is very stable and high water concentration would only drive this reaction forward with the help of enzyme c. Phosphate bonds of ATP is "highly transferable" bonds. d. ATP is very unstable in salt solutions having near neutral pH therefore spontaneously dissociate into ADP and P
