Which description properly describes a step involved in cellular respiration? (3 points) Glucose is broken apart , then the energy gained is transferred to the energy molecule. Carbon dioxide is.combined with oxygen to make glucose. Water is divided into carbon dioxide and glucose. Oxygen is combined with the energy molecule to energize it.

## Step 1<br />Cellular respiration is a process that cells use to produce energy from glucose. This process involves several steps, including glycolysis, the Krebs cycle, and the electron transport chain.<br /><br />## Step 2<br />The first step in cellular respiration is glycolysis, where glucose is broken down into pyruvate. This process releases energy, which is stored in the form of ATP (adenosine triphosphate), an energy molecule.<br /><br />## Step 3<br />The other options provided do not accurately describe the steps involved in cellular respiration. For example, carbon dioxide is not combined with oxygen to make glucose; this is the process of photosynthesis. Similarly, water is not divided into carbon dioxide and glucose; this is not a step in cellular respiration. Lastly, oxygen is not combined with the energy molecule to energize it; oxygen is used in the electron transport chain to accept electrons and form water.
