Answer:
The correct statements are a, b and d. The incorrect statements are c and e.
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 phosphate ions.

Cyclins
are the chemicals that regulate the cell cycle. Cyclins work by regulating the timing
of the cell cycle in eukaryotic cell. Cyclins activates cyclin dependent
kinases (CDKs) (an enzyme that works by adding <span>negatively charged phosphate groups to other
molecules in a process called phosphorylation) by binding to it to form a cyclin-Cdk
complex. This complex then functions by acting as a signal to the cell to move
to the next cell cycle phase. At the end of the event, the cyclin is degraded, Cdk
is deactivated, therefore signaling exit from a specific phase.</span>
