Unit 3: Energy- endergonic vs exergonic reactions

Question 1

endergonic reactions

Answer 1

• require free energy from environment (free energy of system increases)
• nonspontaneous
• anabolic

ex…photosynthesis

Question 2

exergonic reactions

Answer 2

• give free energy to environment (free energy of system decreases)
• spontaneous
• catabolic

ex… cellular respiration
