U3 AOS2: Factors Affecting Rate of Photosynthesis

Front

Light intensity

Back

A factor that affects the rate of photosynthesis, with a plateau indicating a limiting factor or reagent.

Front

Maximum rate (photosynthesis)

Back

The highest rate of photosynthesis that can be achieved under optimal conditions.

Front

Saturation point

Back

The point at which an increase in light intensity no longer results in an increase in photosynthesis rate.

Front

Wavelength

Back

Different wavelengths of light affect the rate of photosynthesis, with violet and red being most effective.

Front

Optimal temperature

Back

The temperature at which enzymes involved in photosynthesis work most efficiently.

Front

Enzyme-substrate

Back

The interaction between enzymes and substrates that facilitates photosynthesis.

Front

Denature

Back

The process by which enzymes lose their functional shape due to high temperature or acidity.

Front

High acidity

Back

A condition that can denature enzymes, affecting the rate of photosynthesis.

Front

Carbon dioxide concentration

Back

A factor that affects the rate of photosynthesis, with a plateau indicating a limiting factor.

Front

Photorespiration

Back

A process that competes with photosynthesis, often involving the enzyme Rubisco.
