Top 10 causes of death worldwide. Of the 56.4 million deaths worldwide in 2015, more than half (54%) were due to the top 10 causes. Ischaemic heart disease and stroke are the worldâs biggest killers, accounting for a combined 15 million deaths in 2015. These diseases have remained the leading causes of death globally in the last 15 years.
Photosynthesis and respiration are reactions that complement each other in the environment. They are in reality the same reactions but occurring in reverse. While in photosynthesis carbon dioxide and water yield glucose and oxygen, through the respiration process glucose and oxygen yield carbon dioxide and water.
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.
