7.3 metabolism pre-vocab

Question 1

Anabolic Reactions

Answer 1

MAKING larger molecules out of smaller ones.

ex. dehydration synthesis or monomers to polymers

Question 2

Catabolic Reactions

Answer 2

BREAKING DOWN larger molecules into smaller ones.

ex. hydrolisis

Question 3

What are some things that ceels do with the energy released when ATP is broken down into ADP?

Answer 3

• Perform chemical reactions w/ enzymes
• Transport power across the cell membrane
• Mechianical work/movement

Question 4

Exergonic reactions

Answer 4

When energy is EXERTED/lost.

(Digesting energy = less organization = lower energy)

Question 5

Endergonic reactions

Answer 5

When more energy is required then what is released.

Question 6

What do Catalysts do?

Answer 6

Reduce the amount of energy that is needed to start a reaction.

(Think of it as more energy efficent, aka low battery mode.)

Question 7

When do Anabolic reactions occur?

Answer 7

With ENDERgonic reactions.

Question 8

When do Catabolic reactions occur?

Answer 8

With EXERgonic reactions.

Question 9

Why do exergonic reactions HAVE to occur before endergonic ones?

Answer 9

Excergonic reactions help set up the energy required for endergonic reactions to take place.
