2.5 Cell metabolism

Metabolic Pathways

Series of chemical reactions within a cell catalyzed by enzymes, converting molecules into different substances.

Anabolic Pathways

Metabolic pathways that synthesize molecules and require energy input.

Catabolic Pathways

Metabolic pathways that break down molecules, releasing energy.

Enzyme Disadvantages

If there is an issue with an enzyme, the metabolic pathway may be disrupted.

Importance of Aerobic Respiration

Aerobic respiration is crucial for metabolic pathways.

Factors Influencing Metabolic Pathways

Temperature, pH, enzymes, chemical inhibitors, and substrate concentration can influence metabolic pathways.

Advantages of Metabolic Pathways

Provide energy for cellular processes, synthesize essential molecules, are controllable, energy-efficient, release small amounts of heat, but large steps can lead to temperature and pH imbalances causing denaturation.
