Unit 1 Lesson 1 Key Question Biology SBI4U-C ILC
1) Mg2+ Has 10 electrons.
2) Carbon -14 would not be effective at dating bones that are millions of years old. Carbon -14 is effective at dating to a maximum of 40 000 to 50 000 years old. The isotope decays over time and would not be present on bones that are millions of years old.
3) Hydrolysis - Water used to breakdown molecules. Hydro means water and lysis means to breakdown. An example of hydrolysis in action within our bodies is how our body breaks down protein into amino acids. Water is used to break protein down in to its amino acids.
Condensation- Condensation is when two molecules combine and form one bigger molecule. It is exact opposite process of hydrolysis. It is also called dehydration synthesis because water is removed “dehydrated” in forming of new molecule. This reaction happens in our bodies when we form muscle tissue.
Oxidization-Reduction (REDOX)- This reaction describes the process of transfer of electrons from one reactant to another. The gaining of electrons is known as reduction and losing electrons is called oxidization. It is usually referred to as REDOX (REDuction/OXidization). One example of redox within our bodies is during cellular respiration. Question 4 is a chemical equation representing this process.
Neutralization - Involves acids and bases and producing water and a salt. Acids contain Hydrogen Ions and Bases contain Hydroxide Ions. The best example of neutralization in our bodies is the carbonic acid bicarbonate buffer. It contains acid and base and maintains our bloods Ph level. If our blood becomes acidic or basic this buffer neutralizes conditions.
4) C6H12O6+6O2-->6CO2+6H2O
a) Carbon atoms in glucose are being oxidized b) Oxygen is being reduced
