Cellular Energy Pre-Lab

Cellular Energy Pre-Lab

Biology & Honors Biology​

we need to understand how oxygen:

• gets into the body

• gets carried to cells so that they can do cellular respiration

and how carbon dioxide:

• gets carried from the cells after cellular respiration

• gets out of the body

​

​Before we do our lab...

Multiple Select

What does food have to do with cellular respiration? (pick 2)

• provides glucose for glycolysis

• provides iron for red blood cells

• provides protein for glycolysis

• provides iron for white blood cells

Multiple Select

What does blood have to do with cellular respiration? (pick 3)

• carries needed O₂ to the cells

• carries CO₂ byproduct to the lungs

• carries needed glucose to the cells

• carries silicon byproduct to the lungs
