|
Enzyme names usually end with what suffix |
-ase |
|
what 3 things do cells need in order to function? |
source of carbon source of energy source of electrons |
|
Why do cells need a carbon source |
because it is the fundamental building block for all organic molecules (carbohydrates, proteins, lipids, nucleic acids) |
|
Why do we need an electron source |
essential part of energy metabolism and because they are needed synthesis of cellular componets |
|
Why do we need a energy source |
because it is needed for processes such as transport, movement, and synthesis of cellular componets. |
|
When NAD accepts electrons it is reduced (gains electrons) to |
NADH+H (often we see NADH2) |
|
Nothing in metabolism happens without the help of an |
enzyme |
|
__________ are things that speed up chemical reactions |
Catalyst (enzymes are biological catalyst) |
|
a pocket on an enzyme is called the |
active site |
|
_______ makes it easier for enzymes to react. |
substrates |
|
___________________ is a series of small steps or chemical reactions strung together where the product of 1 reactions becomes the substrate of the next |
metabolic pathway |
|
These type of organisms obtain their carbon source by eating organic molecules such as sugars, fats, and proteins |
heterotrophs |
|
when oxygen is used in cellular respiration it is called |
aerobic respiration |
|
This step of cellular respiration is simply put as the oxidation of glucose (removing electrons) to 2 pyruvic acids |
Glycolysis |
|
C6H1206--------->C3H403 is the chemical equation for what |
Glycolysis in cellular respiration |
|
The ATP made during glycolysis is made by a process called |
substrate-level phosphorylation |
