Detailed explanation-1: -No catalyst is required for respiration reaction. Reaction takes places in presence of chlorophyll.

Detailed explanation-2: -Photosynthesis and cellular respiration are two biochemical processes that are essential to most life on Earth. Both of these processes involve multiple complex steps and many of the same molecules-oxygen (O2), carbon dioxide (CO2), water (H2O), glucose (C6H12O6), and adenosine triphosphate (ATP).

Detailed explanation-3: -Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly. In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.

Detailed explanation-4: -Both respiration and photosynthesis involve electron transfer across a series of electron carriers embedded in the inner mitochondrial membrane and the thylakoid membranes respectively. Cytochromes are responsible for ATP production through electron transport and are iron-containing proteins.
