5.2 Cell Metabolism Flashcards
1
Q
metabolism
A
all chemical reactions of life
2
Q
anabolic
A
making larger molecules out of smaller ones
3
Q
catabolic
A
breaking down larger molecules into smaller ones
4
Q
exergonic
A
releases energy
5
Q
endergonic
A
requires energy
6
Q
hydrolysis
A
breaking down larger molecules by adding water
7
Q
synthesis
A
joining smaller molecules to create one larger one
8
Q
ATP-ADP cycle
A
- ATP
- phosphate removed
- ADP
- phosphate added
9
Q
exergonic graph
A
reactants have more energy than products
10
Q
endergonic graph
A
reacts have less energy than products
11
Q
anabolic: exergonic or endergonic + example
A
endergonic
dehydration synthesis
12
Q
catabolic: exergonic or endergonic + example
A
exergonic
hydrolysis
13
Q
ATP-ADP cycle: phosphate removed
A
exergonic and catabolic
14
Q
ATP-ADP cycle: phosphate added
A
endergonic and anabolic
15
Q
coupled reactions
A
- cellular respiration (exergonic) and ADP to ATP (endergonic)
- ATP to ADP (exergonic) and protein synthesis (endergonic)
exergonic reactions are not spontaneous. they require some initial input of energy. exergonic reactions must occur before endergonic reactions as the energy released is needed for the endergonic reaction to occur. energonic reactions are spontaneous.
