Bio study (Unit1) Biomolecules

What does biochemistry mean?

• The study of chemical substances and vital processes occurring in living organisms
• The study of the structure and function of biological systems
• The study of the physical and chemical phenomena that occur in the space
• The study of the behavior and interactions among various types of matter

What does Macro-molecules mean?

• LARGE groups of chemicals

• SMALL groups of chemicals

• groups of chemicals bonded together

• groups of molecules chemically bonded

What experiment simulated early-Earth conditions and showed how molecules that we thought only came from life were actually combined from non-living chemicals.

What are factors of an organic molecule

• • - No C-H bonds

  • - EX: CO₂ H₂O

• • - Molecule that makes up living things

  • - Bonds between C-H

What are the factors in inorganic molecules?

• - Molecule that makes up living things

  - Bonds between C-H

• - No C-H bonds

  - EX: CO₂ H₂O

What is dehydration synthesis?

• LInking monomers together to form a polymer

  A water molecule is released

  Releases one less water molecule than the number of monomers

• Cutting polymers into monomers

  Hydrolysis requires water to break apart

What is hydrolysis?

• Cutting polymers into monomers

  Hydrolysis requires water to break apart

• LInking monomers together to form a polymer

  A water molecule is released

  Releases one less water molecule than the number of monomers

What is monomer?

• One; The building blocks of the molecule

• Many; A long chain of monomers linked together

What is a polymer?

• Many; A long chain of monomers linked together

• One; The building blocks of the molecule

What is the function of charbohydrates?

• They are used for muscle contraction
• They provide energy for the body
• They are used for cell division
• They are used for bone growth
