Introduction to Anatomy & Physiology - Part Two

What is the definition of energy?

• Energy is the capacity to do work

• Energy is the ability to create matter

• Energy is the force that stops motion

• Energy is the potential to store heat

The type of energy associated with movement, like a running athlete or flowing water, is (a)   .

• Potential Energy
• Kinetic Energy
• Thermal Energy
• Chemical Energy

What is potential energy?

• Energy that is stored, like in a compressed spring or raised weight

• Energy that is released during combustion

• Energy that is used to power electronic devices

• Energy that is lost as heat

What is catabolism?

• The synthesis of new structures/tissue

• The breakdown of complex molecules/structures/tissue to release energy

• The various chemical reactions occurring in the cell

• The storage of energy in cells

What is anabolism?

• The breakdown of complex molecules/structures/tissue to release energy

• The synthesis of new structures/tissue

• The various chemical reactions occurring in the cell

• The conversion of energy into heat

What does metabolism refer to?

• The storage of energy in cells

• The breakdown of complex molecules/structures/tissue to release energy

• The various chemical reactions that are occurring in the cell

• The synthesis of new structures/tissue

(a)   is an example of a cation important for nerve signals.

• Cl- (chloride)
• Na+ (sodium)
• HCO3- (bicarbonate)
• OH- (hydroxyl)

(a)   is a negatively charged ion essential for pH balance.

• Na+ (sodium)
• K+ (potassium)
• Cl- (chloride)
• Ca2+ (calcium)

What is the primary function of electrolytes in the body?

• To provide energy for cellular processes.

• To conduct electrical charges in body fluids.

• To store genetic information.

• To transport oxygen in the blood.

The role of catalysts in metabolic reactions is that they (a)   .

• Are consumed during the reaction
• Slow down the reaction
• Speed up the reaction without being consumed
• Increase the activation energy required
