|
2
|
|
|
What is the main purpose of cellular respiration?
|

|
|
What are the three main steps of respiration.
|
Glycolysis. Citric Acid Cycle. Electron transport chain.
|
|
|
Describe the structure of an atom.

What is the building block of all matter?
|
Atoms
|
|

Is H2O a polar or non-polar molecule?
|
Polar
|
|
|
What are the six most common elements found in living things?
|
Carbon, hydrogen, oxygen, phosphorous, nitrogen and sulfur.
|
|
|
What do you call all of the chemical reactions that occur in your body?
|
Metabolism
|
|
|
Carbon molecules form what type of bond?
|
Covalent
|
|
|
Substances with a pH between 0-7 are referred to as _______?
|
Acids
|
|
|
What do you call substances that change color in the presence of an acid or a base?
|
Indicator
|
|
|
What can cause an enzyme to become denatured?
|
Extreme heat, pH or strong chemicals.
|
|
|
What happens when an enzyme is denatured?
|
Its active site changes shape and it can no longer function.
|
|
|
Give three reasons why cells divide.
|
To replace dead or injured cells. Growth. Asexual reproduction in unicellular organisms.
|
|
|
What triggers cell division?
|
Cell size. Volume increases faster than surface area.
|
|
|
When do chromosomes duplicate to become sister chromatids?
|
During interphase, right before mitosis.
|
|
|
What is the order of mitosis?
|
PMAT. Prophase, Metaphase, Anaphase, Telophase.
|
|
|
What is occurring during prophase?
|
Chromosomes condense and become visible. Nuclear membrane begins to disintegrate.
|
|
|
What is occurring during metaphase?
|
Chromosomes are lined up at the equator.
|
|
|
What is occurring during anaphase?
|
Sister chromatids are pulled apart and start moving toward the poles.
|
|
|
What is occurring during telophase?
|
New nuclei form.
|
|
|
What is happening during cytokinesis?
|
Division of cytoplasm. In plants, a new cell plate is formed. In animals, the cell pinches in to form a cleavage furrow.
|
|
|
How do cells transport materials into and out of the cell?
|
Diffusion and active transport.
|
|
|
Describe an isotonic solution.
|
A solution in which the solute concentration in a cell is equal to the solute concentration outside the cell.
|
|
|
Explain a hypotonic solution. Give an example.
|
A solution which contains less than normal disolved solutes. An example is distilled H2O.
|
|
|
Explain a hypertonic solution. Give an example.
|
A solution which contains more than normal disolved solutes. An example is salt H2O.
|
|
|
What happens when H2O flows into a cell?
|
The cell's osmotic pressure increases.
|
|
|
What is meant by the term selectively permeable when describing a membrane?
|
It is only going to allow some things to pass through.
|
|
|
What is the function of transport proteins in the plasma membrane?
|
To assist in the movement of particles across the membrane.
|
|
|
Why do scientists refer to the plasma membrane as the fluid mosaic?
|
Made of multiple types of molecules and the phospholipid molecules within the membrane can move like a fluid.
|
|
|
A microscope with an eyepiece lens of 5X and an objective lens of 20X will have a total magnification power of what?
|
100X
|
|
|
What is Robert Hooke famous for?
|
He was the first to observe cork cells and coined the term "cells."
|
|
|
What is Anton Van Leeuwenhoek famous for?
|
He was the first to view living microscopic organisms in pond water and called them animalcules.
|
|
|
What does Theodore Schwann and Matthias Schleiden famous for?
|
They discovered that all animals and plants are made of cells.
|
|
|
What are the 3 statements of the cell theory?
|
1. All living things are made of one or more cells.
2. Cells are the basic units of structure and function in living things. 3. All cells come from other living cells. |
|
|
