8.1 Energy

What is the cell doing when it adds a phosphate to ADP?

• Turning ADP into ATP as a way to store energy for later

• Breaking down carbohydrates for quick energy

• Activating a pump to keep the cell from swelling

The molecule most often used for storing energy in living organisms is

• FBI

• ATP

• ADP

• RNA

This equation represents

• photosynthesis

• a balanced equation for cellular respiration

• a balanced equation for photosynthesis

• the process of osmosis

Heterotrophs use ​ (a)   to break down ​ (b)   , and produce ​ (c)   .

• metabolic pathway

Every time energy is converted from one form to another (like from chemical to mechanical) some energy is lost. What form is lost energy usually in?

• osmotic

• thermal

• wind

• volcanic

What is the fundamental source of energy for all life on Earth?

• natural gas

• the sun

• coal

• wind power

Which gas is removed from the atmosphere during photosynthesis?

• hydrogen
• oxygen
• nitrogen
• carbon dioxide

What does the first law of thermodynamics state?

• The entropy (disorder) of any system will increase over time

• Energy can be converted from one form to another, but it cannot be created nor destroyed.

• metabolism decreases at the point of death

• chemicals are produced when energy combines with water

Autotrophs that convert light energy into chemical energy are called .

• photoautotrophs

• heterotrophs

• chemoautotrophs

• omnivores
