A. Photosynthetic Organisms
photosynthesis takes place in plants, algae, some protests, and cyanobacteria
all of these organisms contain the major photosynthetic pigment chlorophyll a (blue-green)
the structure of chlorophyll is seen on p. 139
Important Biological Molecules
CARBON CHEMISTRY AND FUNCTIONAL GROUPS
carbon has the capability to bond with four other atoms
when carbon is bonded to four atoms, it is saturated and it forms a symmetrical
molecule with a tetrahedral shape
if the four ato
THE CELL - REVIEW
Use the reading package provided to answer the following questions.
Create a table and indicate similarities and differences between prokaryotic and eukaryotic cells
2. a) What is the plasma membrane
b) Describe the structure of the p
A. Cellular Respiration: An Overview
since the beginning of life organisms have evolved mechanisms to harness
environmental energy and convert it into usable forms to power any and all endergonic
processes of life
for example, photoautotrophs, meaning lig
Informational Macromolecules, store hereditary info
Only molecules that can copy themselves
2 types: 1) DNA (deoxyribonucleic acid) and 2) RNA (ribonucleic acid)
Nucleic acids are polymers of monomers called nucleotides linked together
Metabolism and Cellular Energy
the basic characteristics of any living organism is that it grows, repair itself, reproduces,
respires, and eventually dies
to do those things, an organism requires energy
energy is defined as the ability to do work
Read the package entitled cellular membranes and answer the following questions.
1. What are the 3 classes of biological compounds that make up the cell membrane?
b) What is the main role of each of the biological compounds? (In regards
Acids, Bases and Buffers
Hydronium ion (H3O+) is what gives the properties of an acidic solution
Characteristics: sour taste, conducts electricity, turns blue litmus paper red
pH below 7
Acids = substances that increase the concentration of H+ or H
INTRA and INTERMOLECULAR FORCES OF ATTRACTION
INTRAmolecular forces are those bonds WITHIN a molecule, ie. covalent or ionic bonds.
Covalent bonds are very strong and hold atoms together tightly.
Intramolecular forces influence the chemical properties of
