Answer:
Explanation:
Proteins are very sensitive to temperature and pH changes. A pH of 4 is acidic so since the protein is most effective in basic pH (pH above 7) the protein will likely denature or become nonfunctional due to the pH condition being acidic.
The enzyme mentioned in question will only be effective and functional in basic pH whereas, nonfunctional in acidic pH because the acidic pH will affect the structure of protein and if the structure is modified the function is modified as well.
Answer:
B
Explanation:
The cell membrane is made up of a "lipid bilayer" This means that there is are two lipid molecules, each of which has a hydrophilic(water loving) head and hydrophobic(water hating) tail. In the membrane there are 2 molecules facing away from each other such that the head of the lipid faces out and the tail is on the inside. Therefore, with the hydrophobic tail on the inside or center of the membrane it would repel water.
Yes,oxygen and hydrogen together is a compound!
