The answer is granzymes. are serine proteases which trigger the apoptotic cascade in target cells. Apoptotic enzymes activated by granzymes can also destroy viruses or other cytoplasmic pathogens in the target cells so that the pathogens cannot infect nearby cells. Dead target cells are rapidly ingested by macrophages. The Tc cells also produce perforin pores to allow granzymes to enter the target cell.
There are four major protein complexes in the thylakoid membrane: Photosystem II (PSII), Cytochrome b6f complex, Photosystem I (PSI), and ATP synthase. These four complexes work together to ultimately create the products ATP and NADPH.
Both photosynthesis and respiration require specific catalyst.
Why not the other answer?
(1) only photosynthesis require the sun as a source of energy,respiration use glucose.
(2) photosynthesis result in the formation of glucose,respiration result in the formation of carbon dioxide.
(3)Only respiration occur in the mitochondria,photosynthesis occur in the stroma of the chloroplast.
Answer is 2 because both of them require specific enzyme and as you know enzymes are biological catalyst.
