Day 1: Biology SOL Review - Experimental Design and Biochemistry

Front

What is the optimum growth temperature for E. coli?

Back

E. coli has an optimum growth temperature of 30 degrees Celsius.

Front

Where do amino acids link together to form proteins?

Back

Amino acids link together by peptide bonds in the ribosomes.

Front

What type of bond is formed between the negative oxygen atom of one water molecule and the positive hydrogen atom of another?

Back

These attractions are called hydrogen bonds.

Front

What effect does an enzyme have on activation energy?

Back

An enzyme decreases the activation energy required for a reaction.

Front

What happens to water when it freezes in a lake?

Back

When water in a lake freezes, it floats, providing insulation for organisms below.

Front

What is a peptide bond?

Back

A peptide bond is a covalent bond that links amino acids together to form proteins.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are the cellular organelles where proteins are synthesized.

Front

Define hydrogen bonds in the context of water molecules.

Back

Hydrogen bonds are weak attractions between the positive hydrogen atom of one water molecule and the negative oxygen atom of another.

Front

What is the significance of water's low density when frozen?

Back

The low density of frozen water allows ice to float, insulating aquatic life below.

Front

How do enzymes affect chemical reactions?

Back

Enzymes speed up chemical reactions by lowering the activation energy.
