True or false ATP is a portable form of energy currency inside cells?
True.
What produces ATP by blinding phosphate groups to ADP?
ADP is exactly the same as ATP except that ATP has one more phosphate group. (ATP=Adenosine Triphosphate, ADP=Adenosine Diphosphate) This means that adding a phosphate group to ADP would make it ATP simply by definition.
Which of the following is either consumed or synthesized in virtually every cellular reaction?
ATP
Proton pump channels are used to make ADP from ATP during chemiosmosis?
true
Sort the statements into the appropriate bin depending on whether or not they correctly describe some aspect of substrate-level phosphorylation in glycolysis?
Correct Statements:One of the substrates is a molecule derived from the breakdown of glucoseA bond must be broken between an organic molecule and phosphate before ATP can formAn enzyme is required in order for the reaction to occurIncorrect Statements:The phosphate group added to ADP to make ATP comes from free inorganic phosphate ionsThe enzymes involved in ATP synthesis must be attached to a membrane to produce ATP
Which of the following is true of phosphofructokinase (PFK)?
High levels of ATP inhibit PFK
Which of the following is true of glycolysis?
While 2 net ATP are created in glycolysis, there also is a requirement of 2 ATP initially for glycolysis to take place
Which of the following is true about the glycolysis pathway?
There is a net gain of two ATP molecules for each glucose broken down.
ATP synthase catalyzes which of the following reactions?
ADP+Pi→ATP
Which of the following statements about the role of ATP in cell metabolism is true?
The energy from the hydrolysis of ATP may be directly coupled to endergonic processes by the transfer of the phosphate group to another molecule. A key feature in the way cells manage their energy resources to do this work is energy coupling, the use of an exergonic process to drive an endergonic one. ATP is responsible for mediating most energy coupling in cells, and in most cases it acts as the immediate source of energy that powers cellular work.
Which statements regarding the ATP-ADP cycle are true?
NADH and FADH_2 donate their electrons to the chain
True or false-The net gain of ATP from glycolosis is two even though four ATP were actually produced.?
True. It takes 2 ATP to start the reaction and 4 are produced so the net is 2.
Is the ATP CP pathway is sufficient for over four minutes of ATP production?
true
Which of the following is false about the structure and function of ATP synthase?
At least 10 protons pass through ATP synthase in order to make a molecule of ATP.
Is the energy produced by ATP generated by breaking chemical bonds true?
true
Is it true that ATP id required for muscle contraction but not for muscle relaxation?
true
Which of the following couples chemiosmosis to energy storage?
ATP synthase couples chemiosmosis to energy storage.
