BIOCHEM INTRO

Intro to Biochem

QuestionAnswer
universal and versatile solvent water
name the characteristics of water 1. Biological Solvent 2. High heat capacity 3. High heat of vaporization 4. High heat of fusion 5. Medium for chemical and physical processes 6. Means of transport
characteristics of water: ability to dissolve many substances including essential molecules in the body Biological Solvent
characteristics of water: the capacity to retain a large amount of heat, helping in maintaining body temperature high heat capacity
characteristics of water: helps in preventing dehydration in an organism high heat of vaporization
characteristics of water: helps organisms from freezing at low temperature high heat of fusion
can serve as a place for exchanging gases and nutrients and elimination of waste. medium for chemical and physical processes
can serve as a transport/vehicle in the distribution of nutrients, gases and collection of waste products all over the body. means of transport
describe acids - tastes sour - changes color of certain indicators - reacts with some metals and bases - promote chemical reactions such as acid catalysis in a water solution
examples of acids Acetic Acid (vinegar) Ascorbic Acid (Vit C) Citric Acid (citrus fruits) Carbonic Acid Strong Acids (hydrochloric acid (HCL) with pH of 2-4
describe bases -has a bitter taste, slippery and turns red litmus paper to blue
examples of bases - Ammonium hydroxide - Sodium hydroxide - Sodium Bicarbonate -Sodium Carbonate - Calcium carbonate - Potassium Hydroxide - Magnesium hydroxide
describe electrolytes - conducts electricty within the body also known as salts or ions - Ions are classified as cations and anions
why are electrolytes important in biology? because they maintain voltages across the cell membranes and it sends electrical impulses in nerve cells and muscle cells during muscle contraction
examples of electrolytes sodium chloride bicarbonates phosphates sulfate
essential for plants to perform photosynthesis Carbon dioxide
raw materials needed in manufacturing glucose & waste products form the breakdown of organic food substances such as glucose carbon dioxide
