What does it mean for an enzyme to be denatured

To lose its function

Explanation:

Denaturation of macromolecules such as  proteinc or nucleic acid, means that they lose their quaternary structure, tertiary structure, and secondary structure under the influence of a certain factor. The factors that can lead to denaturation are external stress, strong acid or base, a concentrated inorganic salt,  radiation or heat. The consequence of denaturation is loss of biological activity for example, loss of the catalytic ability of an enzyme.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
