Which energy reaction occur in eukaryotic cells and are exact opposites of each other?
A. Fermentation and respiration
Production of glucose and production of ATP
C. Photosynthesis and cellular respiration

C. Photosynthesis and cellular respiration

Explanation:

Photosynthesis uses energy from the sun, carbon dioxide, and water, to produce glucose and oxygen. This is used as a food source in plants.

Glucose is broken down by cellular respiration to release energy in the form of ATP.

Cellular respiration breaks down glucose in the presence of oxygen to produce energy, releasing water and carbon dioxide.

So the reactants and products are switched for these two processes and they could be considered "opposites" of one another.

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.
