What molecule controls the reaction rate of photosynthesis and cellular respiration?

Answer 1

Isolated pea chloroplasts undergo both cyclic and non-cyclic electron flow. Both processes are coupled to photophosphorylation. During non-cyclic flow the rate of oxygen production showed ADP-governed `photosynthetic control' analogous to respiratory control of isolated mitochondria. Measurements of ADP/O and photosynthetic control ratios yielded values of 1-1·3 and 2-5·7 respectively. `Photosynthetic control' was shown to be dependent on the intactness of the chloroplasts.

Answer 2

Phosphofructokinase, PFK, is a rate limiting enzyme going into glycolysis. It is down regulated by an abundance of the energy bearing pathway product, ATP. With activity ATP is consumed and PFK becomes active again so the rate of the respiration pathway increases.

Answer 3

The molecule that controls the reaction rate of both photosynthesis and cellular respiration is adenosine triphosphate (ATP). ATP serves as the primary energy carrier in cells, providing the energy necessary to drive these metabolic processes. By regulating the availability and utilization of ATP, cells can control the pace of reactions involved in photosynthesis and cellular respiration.

Answer 4

enzymes.

It is also affected my some other factors.Some are temperature,light intensity,chloroplast density etc
