If a enzyme denatures, it slows down because:
• It begins to use a new substrate
• it gets bigger and can’t move
• it changes shape and the substrate won’t fit
• it become to small
Answer:
The answer would be "C" because when an enzyme denatures, it changes it shape so that the substrate won't fit anymore. On a side note, when an enzyme is placed in an environment out of its pH or tempertaure range, it can denature.

What role do surface properties play in determining the lifespan of a flu virus?
Answer:
Surface properties have less to do with virus lifespan than does the type of virus. Viruses tend to remain viable for longer on non-porous materials than on porous ones. Viruses tend to remain viable longer on surfaces with low moisture content.
Explanation:
The surface properties in the lifespan of a flu virus are associated with the fact that viruses tend to remain viable for longer on non-porous materials than on porous ones.
Influenza (flu) viruses are contagious viral infections capable of affecting the airways of the lungs.It has been shown that flu viruses survive on human tissues for only 15 min because of their surface properties.Moreover, it has been shown that these viruses cannot survive on non-porous metal/plastic surfaces by more than 9 hours.In conclusion, the surface properties in the lifespan of a flu virus are associated with the fact that viruses tend to remain viable for longer on non-porous materials than on porous ones.
