Honors Biology: Unit 2 Test Questions with Certified Solutions What is the role of the cytoskeleton in the cell? The cytoskeleton provides structural support, helps maintain cell shape, and facilitates movement of materials within the cell. How do plant cells differ from animal cells in terms of organelles? Plant cells have chloroplasts and a large central vacuole, while animal cells do not. Animal cells have lysosomes, which are less common in plant cells. What is the function...

Transport proteins facilitate the movement of molecules across the cell membrane by providing specific pathways for substances to enter or exit the cell. What is the role of the Golgi apparatus in a cell? The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles. How do the two stag...

LifeSci 2A03 Test 1 Questions and Answers 100% Pass What is the primary function of the mitochondria in eukaryotic cells? They produce ATP through cellular respiration, providing energy for various cellular processes. How do lysosomes contribute to cellular homeostasis? They break down and recycle cellular waste, damaged organelles, and macromolecules to maintain cellular balance. What role does the endoplasmic reticulum play in protein synthesis? The rough endoplasmic reticu...

Pancreas and Type 1 diabetes - Answer- The pancreas is the organ that produces insulin, and it plays a major role in regulating blood glucose levels. Type 1 diabetes occurs when the pancreas does not make enough or any insulin. How does insulin work in diabetes? - Answer- Insulin pumps are small, computerized devices that mimic the way the human pancreas works by delivering small doses of short acting insulin continuously (basal rate). The device also is used to deliver variable amounts of in...

Honors Biology Unit 4 Questions and Answers Already Passed What is the primary function of the endoplasmic reticulum (ER) in cells? The ER synthesizes and transports proteins and lipids within the cell. How do vacuoles contribute to cell function? Vacuoles store nutrients, waste products, and help maintain turgor pressure in plant cells. What role do mitochondria play in energy production? Mitochondria generate ATP through the process of oxidative phosphorylation. What is ...
