Example biology quiz questions with answers

Which organelle produces most of a cell's ATP?Mitochondria. They carry out oxidative phosphorylation, which generates most of the cell's ATP.

What is the net ATP yield of glycolysis per glucose molecule?2 ATP. Glycolysis uses 2 ATP in its investment phase and makes 4, so the net gain is 2.

True or false: DNA replication is semiconservative.True. Each new double helix keeps one original strand and one newly synthesized strand.

Which phase of mitosis separates sister chromatids?Anaphase. Spindle fibers pull the sister chromatids toward opposite poles of the cell.

What does a dominant allele do in a heterozygote?It determines the phenotype. A single copy is enough for the dominant trait to be expressed.
