what gas is released during cellular respiration?
co2
n2
o2
h2o

Explanation:

1. For the first question, photosynthesis is only in plants and some microorganisms, fermentation is an anaerobic - related process not universal, chemosynthesis is in certain bacteria. Cellular respiration is the process by which cells break down organic molecules to produce energy and is performed by all living things.
2. For the second question, during cellular respiration, glucose is broken down in the presence of oxygen to produce carbon - dioxide, water, and energy. So carbon - dioxide ($CO_2$) is released.

Answer:

First question: cellular respiration
Second question: $CO_2$
