This energy comes from the food we eat. Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose.
Answer:
D
Explanation:
Low Specific Heat Capacity
A catalyst.
A catalyst speeds up a chemical reaction by increasing the reaction's rate. It does so by decreasing the reaction's required activation energy, which allows the products of the reaction to more easily combine. During this whole process, the catalyst does not change.
Cell is limited in size for many reasons. Cells wouldn't be respire effectively if it were too large, because the surface area to the volume ratio would be too small.
The other thing is that if the cell were too large, it would be difficult for it to move nutrients and waste products in and out of the cell. So, cells are limited in size.
