cava bio 204 s1.d28 2.17 Proteins as Enzymes

QuestionAnswer
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 molecule that an enzyme interacts with is called the substrate, and the region of the enzyme that recognizes the substrate is called the [...] 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.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
