Cell biology (CHEMISTRY)

Question 1

3 building blocks of life

Answer 1

1. Nucleic acid
2. Lipids
3. Amino acids

Question 1

Miller-Urey experiment

Answer 1

1952
Chemical experiment that stimulated the conditions thought to exist on early earth and to test the chemical origin of life under those conditions

Question 2

Oparins and Haldens primordial soup hypothesis

Answer 2

(1924) (1929)
Putative conditions on primate earth favoured chemical reactions that synthesized more complex organic compounds from simpler inorganic precursors

Question 3

Chemical origin of life

Answer 3

Abiogenesis (lifeless beginning)

Simple inorganic chemicals + energy = simple organic chemicals

Question 4

Conclusion of experiment’s

Answer 4

Amino acids (the building blocks of proteins) can be generated in conditions that mimic those of early earth

Question 5

Follow up of experiments

Answer 5

Later experiments have shown that other chemical reactions can generate simple sugars, the bases found in nucleotides, and the lipids needed to form primitive membranes
