Answer:
True
Step-by-step explanation:
Conditions such as temperature and pH are critical for biological molecules and should be well maintained. If the pH changes in an abnormal manner then the structure of the biological molecules might change and they will not be able to perform their functions. For example, the amino acid side chains can be disturbed due to pH changes which result in the unfolding of the protein or the protein structure to get changed, As a result, the protein will not be able to carry out its function. Hence, the statement is true.
