Bio 100 Bioenergetics & Metabolism Mid Term 2

a process that can happen on its own, without input of external energy

• spontaneous

• Anabolism

• Catabolism

• Metabolism

• “Energy coupling

Producing complex molecules from simple molecules

(requires Energy)

• spontaneous

• Anabolism

• Catabolism

• Metabolism

• “Energy coupling

Complex molecules are broken down into simpler molecules

(releases energy)

• spontaneous

• Anabolism

• Catabolism

• Metabolism

• “Energy coupling

Anabolism + catabolism (sum of biochemical/metabolic/cellular reactions of an organism/cell)

• spontaneous

• Anabolism

• Catabolism

• Metabolism

• “Energy coupling

coupling/pairing/linking of catabolic processes (release energy) to anabolism (and other forms of work) which require energy

• spontaneous

• Anabolism

• Catabolism

• Metabolism

• Energy coupling

energy that matter possess as a function of its position/arrangement of its chemical bonds

stored energy

• Chemical Potential Energy

• System

• Surroundings

• Open System
