Honors Biology Semester 2 Final Exam with Complete Solutions What is the role of helicase in DNA replication? Helicase unwinds the DNA double helix by breaking hydrogen bonds between base pairs, allowing replication to begin. How does complementary base pairing ensure accuracy during DNA replication? Complementary base pairing (A with T, C with G) ensures that each new strand is an exact copy of the original template. What is a codon, and how is it related to DNA? A codon is ...

Anaerobic Respiration What is the name of the cell structure that contains enzymes to digest and recycle cellular waste? Lysosome What is the term for the process by which a cell membrane engulfs extracellular material to form a vesicle? Endocytosis What is the name of the pigment found in plant cells...

Honors Biology Unit 3 Test with Complete Solutions What is the primary role of the Golgi apparatus in the cell? The Golgi apparatus modifies, sorts, and packages proteins and lipids for transport to various destinations inside or outside the cell. How does passive transport differ from active transport? Passive transport moves substances across the cell membrane without energy input, while active transport requires energy to move substances against their concentration gradient. ...
