Metobolic Pathway
|
chemical reactions in a cell usually occur in a particular order. They are a metabolic pathway, a series of linked reactions
|
|
|
Enzymes
|
are protiem molecules that function as organic catalysts to speed chemical reactions
|
|
|
Substrates
|
the molecules act on an enzyme are called
|
|
|
Active site
|
one small part of the enzyme accommodates the substrate which fits into the enzyme like a key into a lock
|
|
|
Enzyme inhibition
|
occurs when an active enzyme is prevented from combining with its substrate
|
|
|
feedback inhibition
|
when a product is in abundance it competes with the substrate for the enzyme's active site as the product is used up, inhibition is reduced, and then more product can be produced
|

|
|
What is a chemical compound?
|
2 or more element bonded together
|
|
|
What is the structure of an atom
|
a proton and neutron nucleus surrounded by electrons
|
|
|
How does a atom differ in mass
|
more proton or neutrons
|
|
|
what are their respective charges
|
+ if they have more protons then electrons
- if they have more electrons then protons |
|
|
What is a chemical bond
|
ionic bond ---take an electron
covalent bond they share electrons |
|
|
Hydrogen bond
|
make water stick together is cohesive and adhesive, high water surface tension, high heat capacity, high heat of vaporization, less dense then ice

|
|
|
Chemical reaction
|
A chemical reaction is a process that leads to the transformation of one set of chemical substance. s to another. A Reactant makes a product
6CO2 + 6H2O = C6 H12 O6 + 6O2 Reactant Product |
|
|
Solute
|
dissolved substance: a substance dissolved in another substance
dissolved: dissolved in a solution NaCl salt in water is the solute |
|
|
Solution
|
n chemistry, a solution is a homogeneous mixture composed of only one phase. In such a mixture, a solute is dissolved in another substance, known as a solvent. Salt in water become a solution
|
|
|
Solvent
|
dissolving something: able to dissolve substances
substance that dissolves things: a substance in which other substances are dissolved, often a liquid A property of water through polarity |
