1.
The diagram provided is an incomplete concept map for the process plants use to get energy from food. Which of the following best represents the missing step?
a)
Cellular Respiration
b)
Energy
c)
Atoms Rearranged
d)
Chemical Reaction
2.
How does your body obtain energy from the carbohydrates you eat?
a)
During digestion, large molecules are broken down into smaller molecules, such as carbohydrates broken down into sugars.
b)
The body breaks carbohydrates down into simple sugars, and then the sugars are used as reactants in cellular respiration to release energy.
c)
Photosynthesis is a chemical reaction during which plants convert radiant energy from the Sun to chemical energy. The reaction converts carbon dioxide and water into sugar (glucose), and releases oxygen gas. During cellular respiration in most animals and plants, oxygen reacts with carbon containing molecules (sugars) to provide energy to cells of the organism.
d)
Oxygen is required and energy is released
3.
The energy animals need for their life functions is released when their cells carry out which of the following functions?
a)
Conservation of Matter
b)
Oxygen is required and energy is released.
c)
Organism
d)
Breaking down carbon containing molecules
4.
A naturally occurring element of Earth. An essential building block of organic compounds.
a)
Carbon
b)
Energy
c)
A gas that is natural component of the atmosphere; produced by cells during cellular respiration and used by plants and other organisms for photosynthesis.
d)
Oxygen
5.
Which of the following best summarizes the process of cellular respiration in plants and animals?
a)
Cellular Respiration; sugar

a)
Created; Changes
b)
Cellular Respiration; sugar
c)
Carbon Based Molecules + Oxygen->Carbon Dioxide + Water
d)
Physically; Chemically
12.
What happens to large molecules, such as carbohydrates, during digestion?
a)
Photosynthesis is a chemical reaction during which plants convert radiant energy from the Sun to chemical energy. The reaction converts carbon dioxide and water into sugar (glucose), and releases oxygen gas. During cellular respiration in most animals and plants, oxygen reacts with carbon containing molecules (sugars) to provide energy to cells of the organism.
