Solution:
Photorespiration consumes ATP and NADPH (high-energy molecules). In fact, Photorespiration wastes energy and steals carbon. These molecules are necessary for photosynthesis to synthesize carbohydrates. Therefore, a prolonged period of photorespiration affects the plants because the photorespiration prevents plants from using their ATP and NADPH to synthesize carbohydrates. Remember that carbohydrates are necessary for plants for their own support and their progeny (seeds). Therefore, therefore, photorespiration strongly reduces the photosynthetic capacity of plants, also affecting the normal functions of subcellular organelles.
