Module 1- into

Question 1

what does metabolism refer to

Answer 1

the enzyme catalyzed chemical reactions that occur in a cell to either break down biomolecs to obtain energy in a form our bodies can use (ATP) or reactions that synthesize biomolics that our bodies need

Question 2

what does catabolism refer to

Answer 2

chemical rxns that break down biomolecules to produce energy

Question 3

what does anabolism refer to

Answer 3

chemical reactions that lead to the synthesis of biomolecules that require the input of energy

Question 4

what is metabolism the sum of

Answer 4

the sum total of catabolism and anabolism

Question 5

that are the primary functions of metabolism

Answer 5

1) obtain chemical energy in the form of ATP from the degradation of energy rich nutrients form the environment or form captured solar energy
2) convert molecs we ingest into building blocks for larger molecs needed in the body
3) assemble these small building block molecs into larger molecs such as protein, NA, PS, L
4) to synthesize and degrade biomolecules that have special functions in cell

Question 6

what does the term metabolic pathway decribe

Answer 6

series of linked reactions that begins with particular biomolecule and converts it into another biomolecule in carefully defined fashion that is regulated

Question 7

what are the three ways metabolic pathways can be

Answer 7

linear, branched, circular

Question 8

how can metabolic pathways be interconnected

Answer 8

an intermediate of one pathway can also be an intermediate for one or more other pathways

Question 9

can metabolic reactions be reversible

Answer 9

yes they can be reversible or irreversible depending on the reaction
