Question

The ATP that is generated in glycolysis is produced by substrate-level phosphorylation, a very different mechanism than the one used to produce ATP during oxidative phosphorylation. Phosphorylation reactions involve the addition of a phosphate group to another molecule. Sort the statements into the appropriate bin depending on whether or not they correctly describe some aspect of substrate-level phosphorylation in glycolysis.a. An enzyme is required in order for the reaction to occur
b. A bond must be broken between an organic molecule and phosphate before ATP can form.c. The phosphate group added to ADP to make ATP comes from free inorganic phosphate ions.
d. One of the substrates is a molecule derived from the breakdown of glucosee. The enyzmes involved in ATP synthesis must be attached to a membrane to produce ATP.

Answer 1

Answer:

a,b,and d

Explanation:

Substrate level phosphorylation signifies the generation of ATP from ADP and a phosphorylated intermediate. On the other hand, in oxidative phosphorylation, the formation of ATP takes place from ADP and Pi, that is, an inorganic phosphate.  

In substrate-level phosphorylation an enzyme is needed for the reaction to take place. In the process, a dissociation of bond takes place between an organic molecule and a phosphate prior to the formation of ATP. In this, one of the substrates is a molecule obtained from the dissociation of glucose.  

In substrate-level phosphorylation, the enzyme taking part in the synthesis of ATP is not required to get attached to the membrane to generate ATP. The phosphate group, which is added to ADP to produce ATP does not come from free inorganic.
