Which of the statements about denaturation are true? Protein denaturation involves cleavage of its peptide bonds. A competitive enzyme inhibitor acts by denaturing the enzyme. Denaturation of an enzyme will cause a loss of its catalytic activity. Denaturation and digestion refer to the same process. A denatured protein has a different tertiary structure than its native state. A denatured protein has a different primary structure than its native state.

Human Evolution

Human evolution is the process of evolution of humans from early man to anatomically modern humans. The process of evolution in humans leads to the gradual development of traits like bipedalism. Humans are the highly social animals that make them the most advanced animal on Earth.  Human evolution is an outcome of interaction among the following processes:
