Verified step by step guidance

Understand the role of enzymes: Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy. Their activity is influenced by various factors that affect their structure and function.

Review the factors that influence enzyme activity: Substrate concentration, pH, and temperature are all known to affect enzyme activity. Substrate concentration impacts the rate of reaction until the enzyme becomes saturated. pH affects the enzyme's active site and overall structure, while temperature influences the kinetic energy of molecules and can denature enzymes at extreme levels.

Analyze the factor 'Atmospheric pressure': Atmospheric pressure does not directly affect enzyme activity under normal biological conditions. Enzymes function within cells, where pressure changes are negligible compared to other factors like pH or temperature.

Compare the listed factors: Substrate concentration, pH, and temperature are all critical for enzyme function, while atmospheric pressure is not relevant in typical biochemical contexts.

Conclude that atmospheric pressure does NOT influence enzyme action, as it does not alter the enzyme's structure or function in standard biological environments.
