Metabolism

Question 0

Reactants

Answer 0

Substances that participate in chemical reactions

Question 1

What is metabolism

Answer 1

All the chemical reactions that occur in cells

Question 2

Products

Answer 2

Substances that are formed in a chemical reaction

Question 3

Free energy

Answer 3

Amount of energy that is available to do work after a chemical reaction has occurred

Question 4

Exergonic reactions

Answer 4

Reactions in which energy is released

Question 5

Endergonic reactions

Answer 5

Reaction where energy is absorbed

-can only occur with an input of energy

Question 6

Coupling of reactions

Answer 6

In the body endergonic reactions(absorb energy) like muscle contraction are coupled with exergonic reactions to provide energy

Question 7

Adenosine

Answer 7

Adenine and ribose

Question 8

Adenosine triphosphate

Answer 8

Atp

Question 9

ATP broken down

Answer 9

=ADP+P+free energy

Question 10

Breakdown of glucose is an exergonic reaction or endergonic

Answer 10

Exergonic (energy released)

Question 11

ATP

Answer 11

Generated from ADP+P

Adenosine triphosphate

Question 12

Advantages of ATP as energy carrier

Answer 12

• provides coon energy amount for lots of reactions
• breakdown of ATP to ADP+P releases the perfect amount of energy for biological processes-little energy wasted
• ATP breakdown is coupled with endergonic reactions in such a. Way that it minimizes energy loss
• ATP is very unstable

Question 13

ATP structure

Answer 13

• Modified nucleotide
• Adenine, ribose, three phosphates
• “High energy”compound because the terminal phosphate group is easily removed
