Type in either "anabolic" or "catabolic" in each blank. When we eat, we eat
macroscopic things. But the only way we can absorb the nutrients from our food is
by transporting small molecules across our digestive cell membranes. Therefore,
digestion must occur through

reactions. The small molecule absorbed by our digestive system then enter our blood
to supply all the cells of the body. Each cell type has to use different molecules
within it in order to carry out different functions. So when the nutrients arrive at our
bone cells, those cells will make some different large molecules out of the nutrients
than would occur in, say, fat cells or muscle cells. Taking the nutrients and making
useful, large molecules out of them within a cell would be
considered
reactions.

If we haven't eaten in a while, our liver will take stored, large molecules and break
them down to send nutrients through the blood to supply our body until we can eat
again. If the liver runs out of stored molecules, we then break down the stored fats
inside our fat cells to supply our body with nutrients until we can eat again. Such
actions by the liver and fat cells are considered
