Question

monday. do now week#- tuesday 11. what is the function of enzyme in photosynthesis and cellular respiration.

Explanation:

In photosynthesis, enzymes act as biological catalysts. They speed up the chemical reactions involved, like the conversion of carbon dioxide and water into glucose and oxygen (in the light - independent and light - dependent reactions). For example, RuBisCO (Ribulose - 1,5 - bisphosphate carboxylase/oxygenase) is an enzyme that catalyzes the fixation of carbon dioxide in the Calvin cycle. Without enzymes, these reactions would occur too slowly to sustain the energy needs of the plant and the ecosystem that depends on it.

Answer:

Enzymes in photosynthesis function as biological catalysts, speeding up the chemical reactions (such as the conversion of CO₂ and H₂O to glucose and O₂ in light - dependent and light - independent reactions, e.g., RuBisCO catalyzes CO₂ fixation in the Calvin cycle) that are essential for the process to occur at a rate sufficient to support the plant and the ecosystem.
