Introduction to Biochemistry

Question 1

Where do metabolic reactions take place

Answer 1

in aqueous environments

Question 2

Define condensation reaction

Answer 2

When two or more small molecules combine to form a larger molecule and release water molecule

Question 3

What type of reaction is condensation

Answer 3

anabolic reaction

Question 4

Define anabolism

Answer 4

the synthesis of complex molecules from simpler units, it requires energy

Question 5

Define hydrolysis

Answer 5

When a large molecules is broken down into two or more smaller molecules with the use of water

Question 6

What type of reaction is hydrolysis

Answer 6

catabolic reaction

Question 7

Define catabolism

Answer 7

the breakdown of a complex molecule into simpler units, it releases energy

Question 8

Define photosynthesis

Answer 8

the synthesis of energy-rich molecules from carbon dioxide and water using light energy (anabolic reaction)

Question 9

What is the purpose of cellular respiration

Answer 9

provides energy

Question 10

Explain the potential balancing of oxygen and carbon dioxide in the atmosphere

Answer 10

There is no net production of oxygen or carbon dioxide (the waste products of respiration are the reactants for photosynthesis) the concentration of air remains the same

Question 11

Why do metabolic reactions take place in aqueous environments

Answer 11

• allows to control certain conditions like pH and temperature
