Is the conversion of ADP to ATP endothermic or exothermic?

Is the conversion of ADP to ATP endothermic or exothermic?


Quiz: What is the definition of a coupled reaction? Answer The first reaction (a) is exothermic, giving of energy, while the second reaction (b) is endothermic, requiring energy.
a) ADP + P —–> ATP + H2O Answer Energy on left side
b) ATP + H2O —–> ADP + P Answer Energy on right side

What kind of reaction does ADP phosphorylation is?

ADP is combined with a phosphate to form ATP in the reaction ADP+Pi+free energy→ATP+H2O. The energy released from the hydrolysis of ATP into ADP is used to perform cellular work, usually by coupling the exergonic reaction of ATP hydrolysis with endergonic reactions.

Is phosphorylation of ADP endergonic or exergonic?

endergonic process
ATP (adenosine triphosphate) has three phosphate groups that can be removed by hydrolysis to form ADP (adenosine diphosphate) or AMP (adenosine monophosphate). The phosphorylation (or condensation of phosphate groups onto AMP) is an endergonic process.

What does phosphorylation of ADP create?

Oxidative phosphorylation, the process where electron transport from the energy precursors from the citric acid cycle (step 3) leads to the phosphorylation of ADP, producing ATP.

Is the formation of ADP exothermic?

The ATP forming reaction is an endothermic one , the reverse reaction is exothermic, but for other reactions this may be reverse..

Is breaking ATP exothermic or endothermic?

exothermic reactions
Reactions that produce energy, like ATP hydrolysis, are referred to as exothermic reactions (or sometimes exergonic, meaning roughly the same thing).

How can phosphorylation drive an endergonic reaction?

ATP donates its phosphate group to another molecule via phosphorylation. The phosphorylated molecule is at a higher-energy state and is less stable than its unphosphorylated form, and this added energy from phosphate allows the molecule to undergo its endergonic reaction.

How does ADP turn into ATP?

ADP is converted to ATP for the storing of energy by the addition of a high-energy phosphate group. The conversion takes place in the substance between the cell membrane and the nucleus, known as the cytoplasm, or in special energy-producing structures called mitochondria.

Why is phosphorylation of ADP endergonic?

Phosphorylation is endergonic because it requires energy to form an additional bond with the new phosphate group.

Is the conversion of ADP to ATP exergonic or endergonic?

When a phosphate group is broken off the tail of an ATP molecule (by hydrolysis) the molecule becomes ADP (adenosine diphosphate). That hydrolysis is an exergonic reaction and it yields energy.

When ADP is phosphorylated into ATP a bond between?

ATP is an unstable molecule which hydrolyzes to ADP and inorganic phosphate when it is in equilibrium with water. The high energy of this molecule comes from the two high-energy phosphate bonds. The bonds between phosphate molecules are called phosphoanhydride bonds.

Is oxidative phosphorylation aerobic or anaerobic?

Aerobic vs anaerobic respiration

Aerobic Anaerobic
Location Cytoplasm (glycolysis) and mitochondria Cytoplasm
Stages Glycolysis (anaerobic), Krebs cycle, oxidative phosphorylation Glycolysis, fermentation
ATP produced Large amount (36 ATP) Small amount (2 ATP)
