Rate - GCSE Biology Definition

In GCSE Biology, the term 'rate' refers to how quickly or slowly a biological process happens. It is often used to describe processes, such as the rate of photosynthesis, respiration, or enzyme activity. For example, the rate of photosynthesis refers to how fast plants can convert sunlight, water, and carbon dioxide into glucose and oxygen. Rates can be affected by factors such as temperature, light intensity, and concentration. Understanding rates helps explain how living organisms function and how they respond to changes in their environment.
