What is metabolism?
The sum of all chemical reactions in a living organism.
The breakdown of only carbohydrates and fats to produce energy.
The physical movements that an organism makes.
The process by which organisms respond to stimuli in their environment.
Do all animals obtain food and break it down in a chemical reaction to release energy the same way as humans?
Yes
No
Based on the oxygen and carbon dioxide in the blood percentages, where is the chemical reaction between oxygen and carbon dioxide happening?
Gases entering and returning to the blood from the lungs
Blood going to and returning from other parts of the body
Air inhaled and exhaled
Gases entering into the blood from the lungs and going to other parts of the body

The energy animals need for their life functions is released when their cells carry out which of the following functions?
Breaking down glucose
Absorbing water from the environment
Moving molecules across membranes
Eliminating waste products
What is the best way for the students to use the beads to represent the processes of photosynthesis and cellular respiration that allow plants and animals to get the energy they need?
Take apart all chains and separate the beads by color into groups.
Connect all the beads together into the longest chain that can be made.
Connect different combinations of beads into chains so that no two are alike.
Combine the beads in chains, take them apart, and then put them together in new chains.
The process of obtaining energy from the breaking of chemical bonds in nutrients
Conservation of matter
Cellular respiration
Chemical reaction
