Question

fill in the blanks with the correct term from the word bank below.

• protein
• enzyme
• carbohydrates
• denatured
• specific
• nucleic acid
• lipid

special proteins that help speed up chemical reactions are ____ choose your answer...
a bear will eat many ____ choose your answer... before hibernation to store energy.
if the temperature of an enzyme is too high, it will become ____ choose your answer... and lose its shape.

Explanation:

First Blank:

Enzymes are defined as special proteins that act as biological catalysts to speed up chemical reactions in cells. So the term for "Special proteins that help speed up chemical reactions" is enzyme.

Bears eat carbohydrates (like fruits, plants) which are a source of energy. Carbohydrates are used for energy, and excess can be stored. So the term here is carbohydrates.

When the temperature of an enzyme is too high, it undergoes denaturation, which means it becomes denatured and loses its specific three - dimensional shape (including the active site), which is necessary for its function.

Answer:

enzymes

Second Blank (assuming the context is energy - storage molecules, and the word bank has "carbohydrates", "lipid" etc. But from the given word bank and common knowledge about bear's diet for energy storage, if we consider the options (though the full context of the second blank's sentence is a bit cut off, but from the word bank and typical questions, if it's about energy - storage molecules that a bear eats, "carbohydrates" or "lipid" could be candidates. But since the first part we solved, and for the second blank, if we assume the sentence is "A bear will eat many [molecule] before hibernation for energy storage", and from the word bank, "carbohydrates" or "lipid" are energy - storage molecules. But let's check the word bank again. The word bank has "carbohydrates", "lipid", "protein" etc. If we consider that bears eat a lot of carbohydrates (like berries, etc.) or lipids (like fat - rich foods) for energy storage. But maybe the intended answer is "carbohydrates" or "lipid". Wait, but the user's question has a bit of a cut - off. But let's proceed with the given word bank. If we assume the second blank is about energy - storage molecules, and from the word bank, "carbohydrates" are a source of energy that bears might eat, or "lipid" (fats) for long - term energy storage. But maybe the intended answer is "carbohydrates" or "lipid". However, since the first blank is solved as "enzymes", for the second blank, let's assume the sentence is "A bear will eat many [molecule] before hibernation for energy storage". From the word bank, "carbohydrates" is a common energy - giving molecule that animals eat. So:
