Physical weathering works with mechanical forces, such as friction and impact, while chemical weathering takes place at the molecular level with the exchange of ions and cations.
Oxygen, nitrogen, carbon, hydrogen NOT magnesium
Answer:
Explanation:
The proteins in enzymes are usually globular. The intra and intermolecular bonds that hold proteins in their secondary and tertiary structures are disrupted by changes in temperature and pH. This affects shapes and so the catalytic activity of an enzyme is pH and temperature sensitive.
