The total number of new cases of Crohnâs disease diagnosed each year (incidence) was 10.7 per 100,000 people, or approximately 33,000 new cases per year. The total number of new cases of ulcerative colitis diagnosed each year was 12.2 per 100,000 people, or approxi-mately 38,000 new cases per year (Figure 3).
The most important part of photosynthesis occurs in the chloroplasts. These small photosynthesis factories buried within the leaves house chlorophyll, a green pigment secreted in the chloroplast membranes. Chlorophyll absorbs a wide range of the spectrum of sunlight, giving the plant as much energy as it can for its reactions.
How are photosynthesis and cellular respiration related to each other? Photosynthesis occurs in plants; cellular respiratory occurs in animal life forms. Both processes are used to harvest energy through electron transport. Scientists compare the processes of photosynthesis and respiration by studying the redox reactions present in both processes. Both release energy through the synthesis of ATP. However, redox reactions in photosynthesis and respiration occur in opposite directions.
