preview key concepts
4.1 chemical energy and atp
all cells need chemical energy.
4.2 overview of photosynthesis
the overall process of photosynthesis produces sugars that store
chemical energy.
4.3 photosynthesis in detail
photosynthesis requires a series of chemical reactions.
4.4 overview of cellular respiration
the overall process of cellular respiration converts sugar into atp
using oxygen.
4.5 cellular respiration in detail
cellular respiration is an aerobic process with two main stages.
4.6 fermentation
fermentation allows the production of a small amount of atp
without oxygen.
review biology vocabulary
write the correct word for each definition.
carbohydrate mitochondria enzyme

1. : convert food into usable energy
2. : molecule broken down as a source of energy
3. : decreases activation energy for reactions

preview biology vocabulary
two key terms from this chapter share the same word part. read the
definitions and guess what the word part means.
term definition what i think the word part means
aerobic describes reactions that do not require oxygen
aerobic describes reactions that do not require oxygen

Explanation:

Review Biology Vocabulary Answers:

1. For the first definition "convert food into usable energy", the correct term is mitochondria. Mitochondria are the organelles in cells that perform cellular respiration to convert food (like glucose) into ATP, which is usable energy for the cell.
2. For "molecule broken down as a source of energy", the term is carbohydrate. Carbohydrates (such as glucose) are molecules that are broken down during cellular processes to release energy.
3. For "decreases activation energy for reactions", the term is enzyme. Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to occur.

Preview Biology Vocabulary Answer:

The word part shared by "aerobic" and "anaerobic" is "aer" (or the root related to oxygen). From the definitions, "aerobic" means requiring oxygen and "anaerobic" means not requiring oxygen. So the word part likely relates to oxygen. For example, the root "aer" can be associated with air (which contains oxygen), so the word part probably means something related to oxygen (or air).

Final Answers (Review Biology Vocabulary):

1. mitochondria
2. carbohydrate
3. enzyme
