Carbon Chemistry

Question 1

3 properties of Carbon that allow it to make strong bonds

Answer 1

1) high enthalpy of bond formation (350+ kj/mol)
2) high activation energy for cleavage
3) mid-range electronegativity

Question 2

What type of bond is in inorganic carbon

Answer 2

ionic

Question 3

What type of bond is in organic carbon

Answer 3

covalent

Question 4

Alkanes

Answer 4

(Organic) Carbon bonding to itself and sometimes H or O

general formula CnH(2n+2)

Question 5

role and structure of DNA

Answer 5

information storage
(double stranded)

Question 6

roles and structure of RNA

Answer 6

(single stranded)
catalyst for reactions
gene expression (using information from DNA)
protein synthesis (buildng proteins)

Question 7

How are proteins formed?

Answer 7

Polymerization:
Amine + carboxylic acid -> amino acid
amino acid groups -> peptide
groups of peptides -> protein

Question 8

What is structure of a protein?

Answer 8

linear chain of amino acids (peptides) and folded into a globular form

Question 9

Seven functions of proteins

Answer 9

enzymes that catalyze biochemical reactions (metabolism)
structural
mechanical
cell signaling
immune responses
cell adhesion
guide cell cycle

mnemonic = Cats adhere structure signaling immunity [to] mechanical cycle
