Module 6 Review Exploring Creation with Biology
Question | Answer |
---|---|
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 |
