ATP synthesis occurs both as a part of photosynthesis in the chloroplast and as a part of respiration in the mitochondria. ATP synthesis requires a proton gradient across membrane. Draw and label the parts of a simplified chloroplast and of a mitochondrion. Indicate in each structure where the highest proton concentration occurs and where ATP is made.

See attachment for drawings.

Explanation:

Both cellular respiration and photosynthesis are very important processes that help living organisms perform life activities.

Respiration and photosynthesis involve electron transfer which create an electron gradient and this causes the formation of proton gradient.

Through the proton gradient created, energy is utilized in synthesizing ATP with the assistance of enzyme called ATP synthase.

In chloroplast, the process of transferring electron occurs through photo-phosphorylation which takes place in the presence of light energy.

The electron transport chain in mitochondria is called oxidative phosphorylation which requires chemical energy unlike light energy in chloroplast.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.

b is the correct answer
