How would a temperature drop affect photosynthesis and cellular respiration?

Explanation: The increase in temperature enhances the rate of cellular respiration. It means reactions speed up and rate of cellular respiration increases. When temperature decreases, in order to conserve energy, cellular processes slow.

What happens to cellular respiration when temperature decreases?

The cellular respiration in plants increases with an increase in temperature until the point- when a further increase in temperature will lead to tissue deterioration. When the temperature is decreased, the molecular energy of the reactants is decreased.

What happens to photosynthesis when temperature decreases?

At low temperatures, between 32 and 50 degrees Fahrenheit – 0 and 10 degrees Celsius – the enzymes that carry out photosynthesis do not work efficiently, and this decreases the photosynthetic rate. This leads to a decrease in glucose production and will result in stunted growth.

How does temperature affects the rate of photosynthesis?

The rate of photosynthesis is influenced by temperature. Higher the temperature, greater the rate of photosynthesis. This is because photosynthesis is a chemical reaction and most of the chemical reactions are accelerated with temperature.

How does the rate of photosynthesis affect the rate of cellular respiration?

So the rate of respiration is greater than the rate of photosynthesis. So this means there is an overall excess of carbon dioxide produced during respiration. This means more carbon dioxide is being absorbed by the plant for photosynthesis. So this means more carbon dioxide uptake occurs.

How does cold temperature affect respiratory rate?

When oxygen consumption doubles in response to cold, the minute volume increases by only 40 \% and there is a fall in the oxygen content of the expired air.

Why is the rate of respiration decreases at low temperature?

Relationship Between Photosynthesis and Respiration Levels of oxygen and glucose also affect rates of respiration, and when the balance between photosynthesis and respiration is off, plants often grow with reduced vigor. This helps limit the rate of respiration, as respiration decreases with lower temperatures.

Why does the rate of photosynthesis decrease at low temperatures?

As with any other enzyme-controlled reaction, the rate of photosynthesis is affected by temperature. At low temperatures, the rate of photosynthesis is limited by the number of molecular collisions between enzymes and substrates. At high temperatures, enzymes are denatured .

How does temperature affect the rate of reaction?

Increasing the temperature increases the average speed of the reactant molecules. As more molecules move faster, the number of molecules moving fast enough to react increases, which results in faster formation of products.

What is the relationship between photosynthesis and cellular respiration?

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

What happens when photosynthesis and respiration are equal?

compensation point The point reached in a plant when the rate of photosynthesis is equal to the rate of respiration. This means that the carbon dioxide released from respiration is equivalent to that which is taken up during photosynthesis. The compensation point is reached as light intensity increases.
