Exam 6: Energy Flow in the Life of a Cell

How is your body able to work against the effects of entropy?

In chemical reactions, the are converted into products.

This figure shows the metabolism of glucose and oxygen to CO₂ and H₂O. From what molecule do the carbon in CO₂ and the hydrogen in H₂O come from?

Energy transformations are not 100% efficient. Often, energy is released in the form of , which is in agreement with the second law of thermodynamics.

Describe the biochemical properties of a biological catalyst.

The energy of movement is referred to as energy, and stored energy is referred to as _ energy.

Animals have enzymes that break apart starch molecules but not cellulose, despite the fact that both are made up of glucose subunits. Which enzyme characteristic best explains this?

Briefly describe the difference between kinetic energy and potential energy, and give an example of each.

Coupled reactions are important components of human physiology. Describe an example of a coupled reaction in the human body.

AMP stores energy in its chemical bonds and is able to use that energy for work in the cell.
