energy & ATP

What is the metabolism

All the combined chemical reactions of an organism

Catabolic pathways

Release energy (hydrolysis)

Anabolic pathways

Store energy (dehydration synthesis)

what is the 2nd law of thermodynamics

Every energy transfer increases entropy

What are exergonic reactions

Release free energy

Endergonic reactions

Absorb free energy

what is energy coupling

a biological process in which the energy released by an energy-releasing (exergonic) reaction is used to drive an energy-demanding (endergonic) reaction

what is the #1 energy coupling molecule

ATP

What are the 3 levels of ATP

ATP,ADP,AMP

what does ATP Synthase do

Helps join the phosphate to ADP and forming ATP

What does ATPase do

Helps break the bond involved in removing the last phosphate group using water

Where does photosynthesis take place?

in the mesophyll

Where will CO2, O2, & water vapor diffuse?

Through stomata

T or F: Stomata doesn’t have to be open for photosynthesis

False: Stomata must be turgid and open to perfom photosynthesis

What does the thylakoid membrane have

Pigment molecules (absorb light), electron transport chain molecules, ATP synthase

Describe the structure of chlorophyll

Magnesium center, hydrocarbon lipophilic tail
