If a proteins shape was changed it may be able to do its function to do being unable to fit in all blood vessels/arteries and the shape change may of hindered its capability of carrying nutrients it needs to transport, etc.
for example:
If a hemoglobin (red blood cell) shape changed, (this is normally called sickle cell) the red blood cell would be to unable to travel through the body with ease and easily clog bloodstreams. Also, the hemoglobin will not be able to transport as much oxygen throughout the body.
The five components that make up the total fitness are:
- cardio vascular endurance
- muscular strength
- muscular endurance
- flexibility
- body composition
More energy, better memory, inspiration(I know, it sounds weird but it is true) and we feel more happier
The factor that does not directly influence health is letter B - education. Education actually improves your intellectual wellness. All the other choices are wrong because they all affect some parts of your health like emotional, physical and social. Hope this helps.
