Exploring Creation with Biology Module 6 Study guide

Ribosome (makes proteins) Smooth ER, Rough ER,(make molecules like polysaccharides and lipids) Golgi bodies (package the products), Chloroplasts (involved in photosynthesis), leucoplasts (store products), nucleus (helps through the DNA in itself)
Name the organelles that play a role in biosynthesis

Cytoskeleton, endoplasmic reticulum
What helps the cell hold its shape if it doesn’t have a cell wall?

The cell has a central vacuole that expands as the cell absorbs water.
How does a plant cell fight osmosis in a hypotonic solution?

A cell contains centriols and lysomes. Is it a plant or animal cell?

secretion vessles, golgi bodies, plasma membrane, cell wall
What organelles are involved in secretion?

Cytoplasm, Smooth ER, rough ER, Golgi bodies, secretion vesicles, waste vacuoles, centrioles, cytoskeleton
What things in the cell deal with cellular movement?

absorption, digestion, respiration, biosynthesis, excretion, egestion, secretion, movement, irritability, homeostasis, and reproduction
What are the 11 main functions a cell must perform in order to support and maintain life?

phospholipids, cholesterol, proteins
What is the plasma membrane made out of?

A phospholipid has 2 fatty acid moelcules and a small molecule with a phosphate group.
A normal lipid has 3 fatty acid molecules.
What is the difference between a phospholipid and a regular lipid?

the phospholipids have a hydrophilic end and a hydrophobic end so they know how to reassemble
What makes it possible for the plasma membrane to self-assemble?

active transport
A cell begins running low on food and its energy output decreases by 20%. What kind of plasma membrane transport is affected?

a-phospholipid, b-protien, c-glycoprotein, d-carbohydrate, e-cholesterol, f-filaments of the cytoskeleton, g-glycolipid
Identify the structures pointed out below. (see book #13)

If a cell dies by implosion, what kind of solution was in it?

glycolysis-2, Formation of acetyl conenzyme A-0, Krebs cycle-2, electron transport system-32
List the four stages of aerobic respiration in the order in which they occur and the net number of ATPs that are made in each step.

ATP supplies a package of energy produced in cellular respiration, which releases its energy slowly so the energy doesn’t destroy the cell.
What is ATPs purpose in the cell?

If a cell has no oxygen, what stage of aerobic cellular respiration can still run?

If a cell has no oxygen, how many ATPs can it make from a molecule of glucose?

without ADP, the cell could not make ATP in which to store energy.
A scientist determines a means to extract all ADP from a cell. Why will it kill the cell?

the lysosome
What organelle is responsible for breaking polysaccharides into monosaccharides?

The motion of cytoplasm in a cell that results in a coordinated movement of the cell’s contents.
Cytoplasmic streaming

A solution in which the concentration of solutes is essentially equal to that of the cell that resides in the solution.
Isotonic solution

Collapse of a walled cell’s cytoplasm due to lack of water.

The rupturing of a cell due to excess internal pressure.

The process by which a cell engulfs foreign substances or other cells.

Energy necessary to get a chemical reaction going.
Activation energy

Hypertonic solution
A solution in which the concentration of solutes is greater than that of the cell that resides in the solution

Hypotonic solution
A solution in which the conentration of solutes is less than that of the cell which resides in the solution
