Question

1. what is the general equation for cellular respiration?

carbon dioxide + water + energy → oxygen + glucose
glucose + oxygen → water + energy + carbon dioxide
glucose + energy → carbon dioxide + oxygen + water
carbon dioxide + glucose → water + oxygen + energy

Explanation:

Cellular respiration is a process where glucose reacts with oxygen. It produces carbon dioxide, water, and releases energy. The first option is the equation for photosynthesis (reverse of respiration). The third option misses oxygen as a reactant. The fourth option has incorrect reactants (carbon dioxide and glucose are not the typical reactants for respiration in this way). The second option correctly shows glucose and oxygen as reactants and water, energy, and carbon dioxide as products.

Answer:

glucose + oxygen → water + energy + carbon dioxide (the second option)
