Proteins are involved in light reaction of the photosynthesis are present in the five complexes: thylakoid membrane, photosystems, cytochrome bf complex, thylakoid lumen and ATP synthase. Photosystem I and II in plants are associated with the generation of ATP and NADPH molecules respectively.
If a protein changes their shape in response to temperature it will directly affect the electron transfer chain (will not be transferred) due to which H+ ions transport will also be affected which are involved in the production of ATP molecules.
Thus, option C- a decrease in ATP production is the correct answer.
Xerophytes are plants that have adapted to arid climates. They have evolutionary developed adaptations to reduce the rate of transpiration so as to conserve water.
Among the adaptations include; thick cuticle, small, thick leaves, reducing the surface area relative to the volume of the leaf, etc.
Additionally, they use CAM pathway as an alternative photosynthetic pathway to minimize water loss.
Biological hazards include microorganisms such as bacteria, viruses, yeasts, molds and parasites. Some of these are pathogens or may produce toxins. A pathogenic microorganism causes disease and can vary in the degree of severity
