Question

by which process does yeast produce the carbon dioxide responsible for bread rising? (1 point)
dehydration synthesis.
photosynthesis
cellular respiration
glycolysis

Explanation:

Yeast undergoes cellular respiration in bread - making. In the absence of sufficient oxygen (anaerobic conditions), yeast ferments sugars and produces carbon dioxide gas as a by - product, which causes the bread to rise. Dehydration synthesis is a process for building polymers, photosynthesis is for plants to make food using light, and glycolysis is just the first step of cellular respiration and doesn't solely produce the carbon dioxide for bread rising.

Answer:

cellular respiration
