Global CO2 concentration is rising rapidly. Which type of plants are more likely to benefit from the increased CO2 concentration?

C3 plants benefit most.

Reason why?

Expert Solution

Plants fix carbon dioxide with the help of an enzyme Rubisco. It catalyzes the carboxylation of ribulose-1,5-bisphosphate and produce two molecules of 3-phosphoglycerate. Rubisco has a dual property it can also add molecular oxygen to the ribulose-1,5-bisphosphate, resulting in the formation of one molecule of 3-phosphoglycerate and 2-phosphohlycolate. 2-phosphoglycolate is metabolised through photorespiration. Photorespiration not only consumes energy but also causes net loss of CO₂.

This property of Rubisco is a remnant of the evolutionary history when the atmosphere had high CO₂ concentration and low oxygen concentration. C4 photosynthesis is a way developed by certain plants to cope up with this problem. C4 plants have evolved various anatomical and bio chemical adaptations to increase CO₂ concentration around the Rubisco.

Rise in global CO₂ concentration is having a positive effect on the photosynthesis of C3 plants since high CO₂ concentration is capable of reducing the futile process of photorespiration. A doubling of CO2 may increase photosynthesis rates by as much as 30-100%.

Question 3 In humans, the urge to exhale results from the high concentration of CO2 in the blood. Divers often hyperventilate (rapid breathing for several minutes) prior to making a dive in the belief that this will increase the O2 content in their blood. Use your knowledge of haemoglobin function to evaluate whether this practice is useful. Question 4 Glutathione is a tripeptide, ECG. It contains an unusual peptide linkage between the amine group of cysteine and the carboxyl group...

In order to meet the rising demand from an increasing global population, the United Nations Food and Agriculture Organization had estimated that food production would have to increase by 70 percent to cope with demand. Given the finite supply of arable land and water, producing higher yields through increased farm productivity was seen by many as the only viable option. Biotechnology (Biotech) crops offered one means to increase productivity by offering greater yields while potentially using fewer natural resources such...
