• oxygen

• tannic acid

• dihydrogen phosphate

After eating a large meal, the glucose concentration in the blood increases. When this happens, insulin is released to help transport the excess glucose of of the blood and into specific tissues. The blood glucose concentrations then return to normal. This process is an example of

• respiration

• homeostasis

• metaphase

• immune response

Carbohydrates are used by the body as a source of quick energy, and are made up of

• carbon, hydrogen, and oxygen

• oxygen, hydrogen, and protein

• potassium, oxygen and carbon

• hydrogen, cholesterol, and oxygen

ATP molecules store energy for cellular activity. When the bond holding the third phosphate is broken,

• all cellular activity stops

• energy is released and change ATP to ADP

• energy dissipates and metabolic functions increase

• tRNA picks up the phosphate for protein synthesis

Which statement describes passive transport?

• Substances harmful to a cell are excreted.

• Large molecules move across a membrane.

• A foreign organism transports substances it needs into the cell.
