Mrs. Jackson’s Absolute Bare Minimum Module 1 Review. An organism is any individual living thing. Living things share some common characteristics:. All need energy for metabolism. Metabolism: All of the chemical processes in an organism that build up or break down materials. .
an organism that build up or break down materials.
+Life depends on hydrogen bonds in water.
Charge: Slightly negative
Charge: Slightly positive
<7=Acid (more H+)
>7=Base (less H+)
*Buffer: Helps to maintain pH.
1. Carbon forms covalent bonds (strong bonds) with up to four other atoms, including other carbon atoms (has 4 unpaired electrons in its outer energy level)
2. They can form large, complex molecules
3. Carbon can form single, double, or triple bonds
4. Carbon forms isomers
Monomer called Glucose
monomer-OH + monomer-H polymer + H2O
Dimer called Maltose
Activation energy is the amount of energy that needs to be absorbed to start a chemical reaction
Substrates: reactants that bind to an enzyme
Active site: area on the enzyme where substrates bind
If we keep the concentration of the substrate constant and increase the concentration of the enzyme, the rate of reaction increases linearly.
(That is if the concentration of enzyme is doubled, the rate doubles.)
This is because in practically all enzyme reactions the molar concentration
of the enzyme is almost always lower than that of the substrate.
If we keep the concentration of the enzyme constant and increase the concentration of the substrate, initially, the rate increases with substrate concentration, but at a certain concentration, the rate levels out and remains constant
So at some point, increasing the substrate concentration does not increase the rate of reaction, because the excess substrate cannot find any active sites to attach to.
No nucleus (still have DNA)
No membrane-bound organelles
Smaller size because of lack of organelles
See 3.1/3.2 PowerPoint!
How do membrane-bound organelles facilitate the transport of materials within the cell?
The rough ER works with the Golgi…
There are advantages to being multicellular rather than unicellular. These include allowing:
(repelled by water)
Starch molecule ENERGY)
Glucose molecule4.1 How do living things get ATP?
phosphate removed ENERGY)This is how it works
The first stage of photosynthesis is called the Light Dependent Stage.
The second stage of photosynthesis is called the Light Independent Stage/ Calvin Cycle/ Dark Cycle.
Glucose and oxygen
Carbon dioxide plus water plus light
C6H12O6 + 6O2 6CO2 + 6H2O + 36ATP
