Answer:
ZBWCYAX
Explanation:
Equation for the intermediates: Z↔W↔Y↔X
1) B catalyzes the breakdown of Z, therefore inhibiting B leads to the build up of Z.
2) If enzyme C is inactive then the organism will not receive Y to grow, thus Y is a by-product of C.
3) If A is inhibited then W, Y and Z build except for X, thus it make sense that A catalyzes a reaction that leads to X as a by-product.
4) Inhibiting C leads to the reaction toward making Z and W, thus it catalyzes the breakdown of C directly and Z indirectly.
The general theory is that mitochondria and chloroplasts began initially as separate cells that were "eaten" by larger cells, but not digested and simply passed on due to their advantages.<span />
Answer: Y represents carbon and z is oxygen which gives CO2
Explanation: To photosynthesis to occur Carbon has to reacts with oxygen to give carbondioxide (Co2) which then combines with hydrogen (H2) and oxygen to give water (H20) the reaction gives glucose (C6H12O6).
Equation for photosynthesis = 6CO2+6H20- C6H12O6
