Q: A patient with diabetes has high blood glucose levels. The pancreas releases insulin, causing cells to absorb glucose and lower blood sugar. Which equation best represents this negative feedback process?

$\text{Blood Glucose}_{\text{after insulin}} = \text{Blood Glucose}_{\text{before insulin}} - \text{Glucose Absorbed}$

Q: Which equation best represents the sum of all chemical reactions in the body (metabolism)?

$\text{Metabolism} = \text{Catabolism} + \text{Anabolism}$
