Metabolism Final Review
Across
- 2. In a functioning human body, body systems work _______________ to deliver glucose, oxygen, and amino acid molecules to the cells in the body.
- 5. a molecule that organisms can use to release energy and that is made of carbon, hydrogen, and oxygen atoms
- 7. molecules that are the building blocks of proteins
- 14. the body system that transports molecules to and from all cells of the body
- 16. a group of atoms joined together in a particular way
- 19. The _______________ system brings in oxygen molecules from the air. These oxygen molecules are already small enough to fit into cells.
- 20. a set of interacting parts forming a complex whole
- 21. the body system that takes in food and breaks it down
Down
- 1. Cells can grow and repair themselves by combining ______________ ______________ molecules to form larger protein molecules. This growth and repair requires energy release from cellular respiration.
- 3. the body system that takes in oxygen and releases carbon dioxide
- 4. A problem with a body system can result in fewer oxygen, glucose, and/or amino acid molecules getting to the body’s _______________.
- 6. the ability to make things move or change
- 8. Cells can only use _______________ that are small enough to enter a cell.
- 9. The _______________ system brings in food and breaks it down into smaller molecules, such as glucose and amino acids, that can fit into cells.
- 10. Inside the cell, the atoms that make up glucose and oxygen can be rearranged to make different molecules. This chemical reaction is called __________ __________ and releases energy.
- 11. In order to release __________, cells need both glucose and oxygen molecules.
- 12. the body's use of molecules for energy and growth
- 13. A functioning human body has _______________ from food (glucose and amino acids) and _______________ from air (oxygen) in its cells.
- 15. The _______________ system transports glucose, oxygen, and amino acid molecules to every cell in the body.
- 17. Systems can work together to form a larger more _______________ system.
- 18. a molecule that organisms get from the air or water around them and use to release energy
