Proteins Flashcards
1
Q
Enzymatic Proteins
A
- Functions as an enzyme
- Allows chemical reactions to proceed
- Speeds existing chemical reactions
2
Q
Defensive Proteins
A
- Protects against the organisms which cause disease
Example: Antibodies which bind to substances in the body, can be used by the immune system to identify foreign bodies
3
Q
Structural Proteins
A
- Provides support to major structures such as bones, cartilage, hair, and muscles
Examples: Proteins such as collagen, actin, myosin, and keratin
4
Q
Storage Proteins
A
- Stores amino acids
5
Q
Transport Proteins
A
- Act as doors to the cell, helping certain molecules pass back and forth across the plasma membrane
6
Q
Hormonal Proteins
A
- Act as chemical messengers that aid communication between your cells, tissues and organs
7
Q
Receptor Proteins
A
- Response of cell to chemical stimuli (think: smells going through your nose to be registered in brain)
8
Q
Motile/Contractive Proteins
A
- Facilitates movement
Example: Contraction of muscles
9
Q
Amino Acids
A
Monomer of protein
10
Q
How do you form a protein?
A
Multiple “linked” amino acids through peptide bonds
11
Q
Peptide Bond
A
A type of covalent bond that connects amino acids to form proteins
12
Q
What creates a peptide bond?
A
A condensation reaction (GENERATES water)
13
Q
What do peptide bonds form between?
A
The amino group of one amino acid and the carboxyl group of another
14
Q
What influences the shape of proteins?
A
The physical shape of the amino acids that make it up, they force the newly formed protein into a specific shape
15
Q
What are the four shapes of proteins?
A
Primary, Secondary, Tertiary, Quarternary
