Question

Does higher temperature increase photosynthesis?

Answer 1

Hint: Temperature. The rate of photosynthesis is affected by temperature, much like any other enzyme-controlled reaction. The number of molecular collisions between enzymes and substrates limits the pace of photosynthesis at low temperatures. Enzymes are denatured when exposed to high temperatures.

Complete answer:
The temperature has an impact on the rate of photosynthesis. The rate of photosynthesis increases as the temperature rises. Because photosynthesis is a chemical reaction, and most chemical reactions are increased by warmth, this is the case. However, in the case of photosynthesis, a temperature exceeding 40 °C slows down the process. Because it is an enzyme-controlled process, this is the case. It occurs as a result of enzymes being involved in temperature-sensitive chemical processes. The enzymes simply stop working and get denatured at higher temperatures. This is true even after carbon dioxide diffusion into the leaves has increased.

At lower temperatures, the number of molecular collisions between the substrate and the enzymes limits the pace of photosynthesis. A temperature range of 25° to 35° C is required for photosynthesis to be carried out efficiently. There are also several other factors that influence photosynthesis, such as – carbon dioxide pollution levels, water availability, and light intensity.

Photosynthesis is influenced by the following factors:
i) Carbon dioxide - an increase in carbon dioxide concentration can boost photosynthetic rates.
ii) The rate of photosynthesis is affected by the intensity and quality of light.
iii) The temperature has an impact on photosynthesis. High temperatures induce enzymes to become inactive, making photosynthesis vulnerable to greater temperatures.
iv) Photosynthesis necessitates aeration. Oxygen is essential for electron transport in modest amounts.
v) Nitrogen has been shown to affect the rate of photosynthesis.
vi) The photosynthetic rate is slowed by contaminants in the air, Soil, pH, and other climatic factors all play a part.

There are also other internal variables that influence photosynthesis, such as –
-Anatomy of the Leaf.
-Plant hormones Chlorophyll.
-End-product accumulation.
-RuBisco's performance.
-The Calvin Cycle's enzyme activity.
-Chloroplasts Percentage Transport of electrons.
-Stomatal characteristics. The capacity of metabolite transport mechanisms to use carbon

For all plants, the rate of photosynthesis does not increase as the temperature rises. Plants that grow in colder climates have a photosynthetic rate that is optimal at low temperatures. As a result, different species of plants have varying photosynthetic optimal temperatures.

Note: The photosynthetic enzymes perform at their best at medium temperatures, between 50 and 68 degrees Fahrenheit (10 and 20 degrees Celsius), hence photosynthesis rates are high. Set the greenhouse thermostat to a temperature within this range for best outcomes, depending on the plant in the issue.
