What process occurs in box a?
a. electron transport and oxidative phosphorylation
b. glycolysis
c. the citric acid cycle
d. oxidative phosphorylation
e. electron transport

Explanation:

Glycolysis is the first phase of cellular respiration. It is the degradation of glucose into small molecules to yield ATP (cellular energy).

Box A is the cytosol where Glycolysis occurs. This is mainly due to the high concentration of glucose and other related enzymes.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
