cava bio 204 s1.d28 2.17 Proteins as Enzymes
Question | Answer |
---|---|
Catalysts are chemicals that speed up a reaction without being [-ed]. | Catalysts are chemicals that speed up a reaction without being destroyed. |
Enzymes are catalysts that are [-s]. | Enzymes are catalysts that are proteins. |
Why do we need a separate word for catalysts when they happen to be [-s]?.... So you get to memorize even more words!!! :-) | Why do we need a separate word for catalysts when they happen to be proteins?.... So you get to memorize even more words!!! :-) |
Lactase is an enzyme that speeds the breakdown of [...] into glucose and galactose. | Lactase is an enzyme that speeds the breakdown of lactose (milk sugar) into glucose and galactose. |
[...] names tend to end in '-ase' | Enzyme names tend to end in '-ase' |
[...] names tend to end in '-ose' | Sugar names tend to end in '-ose' |
All enzymes are proteins, but not all proteins are [-s]. | All enzymes are proteins, but not all proteins are enzymes. |
Common Enzyme groups: 1. Amylase - breaks down [...] 2. lipase - breaks down lipids 3. protease - breaks down proteins | Common Enzyme groups: 1. Amylase - breaks down starches 2. lipase - breaks down lipids 3. protease - breaks down proteins |

Every enzyme catalyzes (speeds up) a [...] reaction. | Every enzyme catalyzes (speeds up) a specific reaction. |
The molecule that an enzyme interacts with is called the [...], and the region of the enzyme that recognizes the [...] is called the active site. | The molecule that an enzyme interacts with is called the substrate, and the region of the enzyme that recognizes the substrate is called the active site. |

The end results of ANY AND ALL chemical reactions (whether they include a catalyst or not) are called [-s]. | The end results of ANY AND ALL chemical reactions (whether they include a catalyst or not) are called PRODUCTS. |
The amount of energy required for a reaction to take place is called [...] energy. Enzymes speed up chemical reactions by lowering [...] energy. | The amount of energy required for a reaction to take place is called activation energy. Enzymes speed up chemical reactions by lowering activation energy. |
Enzyme-assisted reactions reach a maximum [...]; enzymes speed up reactions, they don't work magic. | Enzyme-assisted reactions reach a maximum rate; enzymes speed up reactions, they don't work magic. |
When all the enzyme molecules are busy (all bonded to substrate), we say that the enzyme is [...]. | When all the enzyme molecules are busy (all bonded to substrate), we say that the enzyme is saturated. |
Once the enzymes are saturated, the reaction doesn't proceed any faster: It's at its [...] rate. | Once the enzymes are saturated, the reaction doesn't proceed any faster: It's at its maximum rate. |
Certain enzymes also require other compounds, such as the minerals zinc (Zn) and copper (Cu). Those compounds are called [-s]. | Certain enzymes also require other compounds, such as the minerals zinc (Zn) and copper (Cu). Those compounds are called cofactors. |
Like all proteins, enzymes are sensitive to changes in their [...], such as temperature, pH, and ionic conditions. And each enzyme has a specific set of conditions that are ideal for its activity. | Like all proteins, enzymes are sensitive to changes in their environment, such as temperature, pH, and ionic conditions.
