Verified step by step guidance1
Understand the role of enzymes: Enzymes are biological catalysts that speed up chemical reactions in cells without being consumed in the process.
Consider the impact on reaction rates: Without enzymes, reactions would still occur but at a much slower rate, as enzymes lower the activation energy required for reactions.
Evaluate energy production: Enzymes help regulate energy production by facilitating efficient metabolic pathways. Without them, energy production would be less efficient and slower.
Assess metabolic efficiency: Enzymes contribute to the efficiency of metabolic processes by ensuring reactions occur quickly and under optimal conditions. Without enzymes, these processes would be less efficient.
Conclude the overall effect: Biological processes would continue but at a significantly reduced rate, affecting the organism's ability to sustain life functions effectively.
