In negative control, Repressor molecule is expected to be bound to the operator is there is no transcription.
Repressor molecule is a small protein which binds with the operator gene and prevents it from starting the synthesis of proteins called operon. The repressor molecule controls the amount of enzyme synthesis by reducing its rate of formation. The lac repressor is a protein that represses (inhibits) transcription of the lac operon. In negative control, repressor molecule binds with the DNA molecule and blocks transcription process. A negative control is an experimental control that does not give a response to the test. The system of regulation in lactose and tryptophan operons outlined above is essentially a negative control.

Answer:
How is it regenerated? When the F1 portion of the ATP synthetase complex is removed from the mitochondrial membrane and studied in solution, it functions as an ATPase. Why does it not function as an ATP synthetase? The standard free-energy change for ATP hydrolysis is -30.5 kJ/mol.
B. Dark
Any of the chemical reactions that take place during the second stage of photosynthesis and do not require light. During the dark reactions, energy released from ATP (created by the light reactions) drives the fixation of carbon from carbon dioxide in organic molecules.
