Answer:
These 3 receptors are different from each other. They do differ from each other by their location and function.
1. Testosterone receptor :  It is an Androgenic receptor
2. Ferrotransferrin receptor :  It acts as an element-binding protein which is iron responsive.
3. Fibroblast growth factor :  It acts as a growth factor.
Explanation:
1. Testosterone :
Location- Xq 11-12 in the X chromosome.
Function-  
-  maintains male skeletal integrity by osteoblast and osteocytes.
- maintains female sexual, somatic and behavior.
- develops male sexual characters.
2. Ferrotransferrin :
Location- chromosome 3q21
Function-
- intakes iron in the cell.
- maintains the cellular iron equilibrium.
- post-transcriptional modification.  
3. Fibroblast (growth) :
Location- chromosome 4p16.3
Function-
- helps in bone development.
- helps in bone growth maintenance by ossification.

Answer:
The correct answer is - false statement.
Explanation:
The statement mentioned in question explaining the process of metabolism. Metabolism is a procedure that includes catabolic and anabolic process that which are chemicals reactions takes place in the body. Metabolism is breaking large molecules into simpler and simpler molecules to synthesizing complex molecules from simpler molecules.
Digestion is the process in which ingested food break down to simpler substances and absorbed to provide nutrients to body.
Thus, the correct answer is - false statement.
