What is metabolism?

• All of the chemical reactions that take place inside of a cell

• Food in food out

• All of the chemical reactions that take place outside of a cell

What is an endergonic reaction?

• Reaction that needs input of energy, consumes energy

• Reaction that happens spontaneously, no input of energy needed but releases energy.

Endergonic reactions:

• Break down molecules, and produce energy

• Break down molecules, and consume energy

• Build up molecules, and produce energy

• Build up molecules, and consume energy

What is an exergonic reaction?

• Reaction that happens spontaneously, no input of energy needed but releases energy.

• Reaction that needs input of energy, consumes energy

What are the 3 laws of thermodynamics?

• Energy not destroyed nor created

• Entropy, how disordered a system is, or how much energy is unavailable to do work.

• Entropy and temperature related. If system reaches absolute 0 K (ultimate freeze temp, no movement of molecules) then entropy is at minimum.

• Energy can be created but not destroyed

What is the 1st law of thermodynamics?

• Energy not destroyed nor created

• Entropy, how disordered a system is, or how much energy is unavailable to do work.

• Entropy and temperature related. If system reaches absolute 0 K (ultimate freeze temp, no movement of molecules) then entropy is at minimum.

What is the 2nd law of thermodynamics?

• Energy not destroyed nor created

• Entropy, how disordered a system is, or how much energy is unavailable to do work.

• Entropy and temperature related. If system reaches absolute 0 K (ultimate freeze temp, no movement of molecules) then entropy is at minimum.

What is the 3rd law of thermodynamics?

• Energy not destroyed nor created

• Entropy, how disordered a system is, or how much energy is unavailable to do work.

• Entropy and temperature related. If system reaches absolute 0 K (ultimate freeze temp, no movement of molecules) then entropy is at minimum.

What increases entropy?

• Increased movement of molecules & breaking down molecules

• Increased movement of molecules & building up molecules

• Decreased movement of molecules & building molecules

• Decreased movement of molecules & breaking down molecules

What is depolymerization?

• Process of breaking down monomers into smaller molecules called polymers

• Process of building polymers into smaller molecules called monomers

• Process of breaking down polymers into smaller molecules called monomers
