For an enzyme to be able to catalyze a reaction, the active site must --

• be occupied by an inhibitor

• increase the activation energy level

• have a complementary shape to the substrate

• cause the enzyme to be destroyed in the reaction

Enzymes are proteins that have a three-dimensional shape that is specific to a particular substrate. Environmental conditions can change the shape of the protein.

What is the most likely result if the shape of the enzyme changes?

• The substrate will change its shape to match the enzyme.

• The enzyme will no longer be able to catalyze the reaction with the substrate.

• The products made from the enzyme and the substrate will be changed.

• The enzyme will be able to bind to more diverse substrates than before.

Which system must interact with the respiratory and digestive systems to transport gases and nutrients throughout the body?

• endocrine

• integumentary

• immune

• circulatory

Which statement best describes an interaction between the muscular system and the respiratory system?

• The hormone adrenaline causes blood vessels to contract and send more blood to major muscles.

• Metabolic wastes generated by muscle cells are eliminated in urine.

• The diaphragm contracts causing the chest cavity to expand, which draws air into the lungs.

• Nutrients absorbed in the small intestine are transported in blood to the brain.

Which four body systems interact to allow a person to sneeze?

• muscular, immune, nervous, respiratory

• nervous, respiratory, circulatory, skeletal

• respiratory, endocrine, skeletal, circulatory

• lymphatic, skeletal, respiratory, muscular
