Bioenergetics Flashcards
What is stored energy called?
Potential energy
How is chemical potential energy stored?
Bonds
How is energy stored When having undergone photosynthesis?
Glucose
How much energy dues glucose store?
2831 Kj 1mol
Cellular work and glucose
Active transportuses 30 kj of energy and if glucose was used then there wold be 95x more energy
ATP
Smaller energy package
Cellular respiration breaks bonds and the energy istransfered from glucose to molecules
1st law thermodynamics
Energy cannot be created or destroyed any change forms
2nd law theromodynomns
Entropy
The more every transformed the more random and disorder results from that used’ energy
How is the earth being protected by entropy
Sun
Metabolism
All physical and chemical reactions associated with life
Catabolism
Break down release every
Anabolism
Make bigger require energy
Bond energy
Amount of energy need to make chemical bond = amount of every released when chemical bond is broken
Free energy
Amount of energy available (stored or released) to do chemical work
Endergonic
Energy absorbed
Not spontaneous
G>0
