Review Module 6

Module 6 Review Exploring Creation with Biology

QuestionAnswer
Name the organelles that play a role in biosynthesis. Ribosome, Smooth ER & Rough ER, Golgi Body, Chloroplast, Leucoplast, Nucleus, Secretion Vesicle
What is the role of the ribosome in biosynthesis? Makes proteins
What are the roles of the smooth ER and rough ER in biosynthesis? Make molecules such as polysaccharides and lipids
What is the role of the Golgi body in biosynthesis? Packages products of biosynthesis
What is the role of the Chloroplast in biosynthesis? Contains chlorophyll, which is a catalyst for photosynthesis
What is the role of the Leucoplast in biosynthesis? Stores starches or oils
What is the role of the nucleus in biosynthesis? Participates in the production of protein through the DNA that it contains
What is the role of the secretion vesicle in biosynthesis? Move products of biosynthesis to plasma membrane for secretion
What helps the cell hold its shape if it does not have a cell wall? Cytoskeleton and endoplasmic reticulum
How does a plant cell fight osmosis in a hypotonic solution? The cell has a central vacuole that expands as the cell absorbs water. This causes turgor pressure in the cell, which counteracts osmosis.
A cell contains centrioles and lysosomes. Is it a plant or animal cell? Animal cell
What organelles or parts of the cell are involved in secretion? Golgi body, Secretion vesicle, Plasma Membrane, Cytoplasm
What parts of the cell deal with cellular movement? Cytoplasm, Smooth ER, Rough ER, Golgi body, Secretion Vesicles, Waste Vacuoles, Centrioles, Cytoskeleton, Plasma Membrane
What are the eleven major tasks cells must perform? Absorption, Biosynthesis, Digestion, Egestion, Excretion, Homeostasis, Irritability, Movement, Reproduction, Respiration, Secretion,
What is the difference between a phospholipid and a regular lipid? A phospholipid has two fatty acid molecules and a small molecule with a phosphate group, whereas a normal lipid just has 3 fatty acid molecules.
What makes it possible for the plasma membrane to self-assemble? Phospholipids have a hydrophilic end and a hydrophobic end, they always "know" how to reassemble.
A cell begins running low on food, and its energy output decreases by 20%. What kind of plasma membrane transport is affected? Active transport
If a cell dies by implosion, what kind of solution was it in? Hypertonic solution
List the four stages of aerobic cellular respiration in the order in which they occur and give the net number of ATPs made in each step. Glycolysis(2), Formation of acetyl coenzyme A(0), Krebs cycle(2), Electron transport system(32)
What is ATP's purpose in the cell? Supplies a package for the energy produced in cellular respiration in order to release the energy gently, thus preventing cell destruction.
If a cell has no oxygen, what stage of aerobic cellular respiration can still run? How many ATPs can it make from a molecule of glucose? The cell can only run glycolysis, which can only make two ATPs per molecule of glucose.
A scientist determines a means to extract all ADP from a cell. Why will this kill the cell? With no ADP, the cell can't make ATP in which to store the energy, so the cell could not use the energy produced.
What organelle is responsible to breaking polysaccharides in to monosaccharides? Lysosome
A cell produces a protein that will be used by other cells. When it ejects the protein, what action has it performed? Secretion
What lies between the cell walls of a plant's cells? Middle lamella
What organelle does rough ER have? Ribosome
Before a polysaccharide can be used in cellular respiration in an animal cell, to what organelle must it be sent? To the lysosome to be broken down into monosaccharides
If a cell's mitochondria stop working, can it perform any cellular respiration? Yes, some, but only glycolysis, which occurs in the cytoplasm
Which provides more energy per molecule of glucose: respiration in aerobic conditions or respiration in anaerobic conditions? Aerobic conditions
Which stage in cellular respiration produces the most energy? Electron transport system
Which two stages in aerobic cellular respiration produce equal amounts of ATP? Glycolysis and Krebs cycle
