Answer:
lower
Explanation:
<em>Enzymes are chemical substances or biological molecules that catalyze biological reactions by lowering the activation energy threshold required to start such reactions.</em>
The activation refers to the minimum energy that must be conquered by the reactants in a chemical reaction in order to cross over to the product's side.
Enzymes work by lowering this energy and hence, making the crossing over to the product's side faster than normal. They are not themselves used up in reactions and can always be recovered and reused.
<em>Correct answer</em>: lower
Answer:
Thermophiles have heat-resistant enzymes.
Explanation:
A hypothesis refers to the possible explanation of processes and is based on observation.
Thermophiles are able to survive the extremes of the temperature found in hot springs of Yellowstone National Park. Their ability to withstand such temperature may be due to the presence of heat resistant enzymes.
Since enzymes are proteins, they are denatured at higher temperatures. It is one of the factors that determine the temperature range that can be tolerated by an organism.
Hence, the presence of heat resistant enzymes in thermophiles can be one of the possible explanations about their ability to survive under the temperature as high as 205 degrees Fahrenheit.
After break down food may be used in the body to provide energy, as building blocks for tissue and cells, and can be stored for future use.
The body uses food for energy, for growth by making new cells and repairing or replacing tissues, may be stored by converting it into glycogen or fat before they can be stored. The main types of foods are carbohydrates, proteins and fats.
