Diverse shapes allow proteins to carry out many functions. Name the six divers shapes.
What is the function of a Structural protein?
Form structural framework of various parts of the body.
Ex: collegen in bone and other connective tissues, and keratin in skin, hair, and fingernails.
What is the function of a Regulatory protein?
Function as hormones that regulate various physiological processes: control growth and development; as neurotransmitters, mediate responses of the nervous system.
What is the function of a Contractile protein?
Allow shortening of muscle cells, which produces movement.
Ex: myosin and actin
What is the function of a Immunological protein?
Aid responses that protect body against foreign substances and invading pathogens.
Ex: antibodies and interleukins.
What is the function of a Transport protein?
Carry vital substaces throughout body.
Ex: hemoglobin, which transports most oxygen and some carbon dioxide in the blood.
What is the function of a Catalytic protein?
Act as enzymes that regulate biochemical reactions.
Ex: Salivary amylase, sucrase, and ATPase.
Chemical reactions either absorb or _________ energy.
Substance undergoing reaction =
Enzyme names almost always end in
What splits the disaccharide sucrose into glucose and fructose?
What are the fat-soluble vitamins
What is the monomer for both DNA and RNA?
What are the Nucleic acid bases:
- Thymine (DNA)
- Uracil (RNA)
What is the nucleic acid sugars
- Deoxyribose (DNA)
- Ribose (RNA)
Nucleotides have 3 parts, what are they?
A five-carbon sugar or pentose
A cyclic, nitrogen-containing base
Nucleotides are monomers of
The overall structure of DNA is known as the
double helix and cosists of two twisted strands.
The DNA and RNA molecules have a backbone which is made up of the
The A-T combination forms how many hydrogen bonds
The C-G combination forms how many hydrogen bonds
What is more stable DNA or RNA?
Compare and contrast DNA and RNA
DNA is the permanent set of instructionf for the organism.
RNA is a "scratchpad" molecule that is used for temporary storage and manipulation of genetic information as it is expressed as a protein.
- DNA uses the four bases A, C, G and T.
- RNA uses the four bases A, C, G and U.
- DNA is usually in a double helix
- RNA is generally found in a single-stranded form
What do "squiggles" represent
High energy bonds ATP
Cellular pathways that require energy are adapted to use
ATP as their energy source
What is used as the energy currency for the cell?
What is the secret of ATP?
High-energy phosphate bonds
Forms of cellular energy. What are the types of energy?
- Potential (chemical)

What bioenergetic event does heat produce?
Cellular chemical reactions
What bioenergetic event does mechanical produce?
What bioenergetic event does potential (chemical) produce?
Energy-rich covalent bonds
What bioenergetic event does radiant produce?
photosynthesis in plants
