True or false:proteins are needed for tissue growth and repair
- A.
Maybe
- B.
Not sure
- C.
False
- D.
True
Correct Answer
D. TrueExplanation
Proteins are essential for tissue growth and repair. They are made up of amino acids, which are the building blocks of our body. When we consume proteins through our diet, they are broken down into amino acids that are used to repair and build new tissues. These tissues include muscles, organs, skin, and bones. Without an adequate intake of proteins, our body would not have the necessary materials to repair damaged tissues or support growth. Therefore, the statement that proteins are needed for tissue growth and repair is true.Rate this question:

True or false:Proteins play an important part in chemical reactions within cells
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Proteins are known to be involved in various chemical reactions within cells. They act as catalysts, known as enzymes, that facilitate and speed up these reactions. Enzymes bind to specific molecules and help convert them into different forms, allowing essential cellular processes to occur. Without proteins, many crucial chemical reactions necessary for cell function would not take place efficiently or at all. Therefore, it is true that proteins play an important part in chemical reactions within cells.Rate this question:

glucoseExplanation
Glucose is the major source of energy for the body's cells. It is a type of sugar that is broken down by the body to produce ATP, which is the primary energy currency of cells. Glucose is obtained from the digestion of carbohydrates in the diet and is transported through the bloodstream to provide energy for various cellular processes. It is particularly important for brain function, as the brain relies heavily on glucose for energy.Rate this question:
- 18.
What can the body convert in order to make glucose
Correct Answer
sugar in fruitExplanation
The body can convert sugar in fruit into glucose. Glucose is a simple sugar that is the primary source of energy for our body's cells. When we consume fruits that contain sugar, the body breaks down the sugar molecules and converts them into glucose through a process called glycolysis. Glucose is then used by our cells to produce energy through cellular respiration. Therefore, sugar in fruit can be converted by the body into glucose to meet its energy needs.Rate this question:
- 19.
True or false:glucose is the form of sugar the body can most easily use
Correct Answer
trueExplanation
Glucose is indeed the form of sugar that the body can most easily use. It is a simple sugar that is readily absorbed into the bloodstream and used as a source of energy by cells. Glucose is the primary fuel for the brain and muscles, and it plays a crucial role in various bodily functions. Other forms of sugar, such as fructose and sucrose, need to be broken down into glucose before they can be utilized by the body. Therefore, glucose is the preferred and most easily usable form of sugar for our bodies.Rate this question:

Blank are made of many sugar molecules linked together in a chain.
Correct Answer
complex carbohydratesExplanation
Complex carbohydrates are made up of many sugar molecules linked together in a chain. They are called "complex" because their structure is more intricate compared to simple carbohydrates. Complex carbohydrates provide a slow and steady release of energy as they take longer to break down in the body. Foods rich in complex carbohydrates include whole grains, legumes, and vegetables.Rate this question:
- 21.
What is starch?
Correct Answer
a complex carbohydrateExplanation
Starch is a complex carbohydrate. Carbohydrates are one of the three main macronutrients, along with proteins and fats, that provide energy for the body. Starch is a polysaccharide, meaning it is made up of many sugar molecules bonded together. It is the main storage form of energy in plants and serves as a source of dietary energy for humans and animals. Starch is broken down into glucose during digestion, which can then be used by the body for energy or stored for later use.Rate this question:
- 22.
Where is starch found
Correct Answer
plant such as potatoes, rice, wheat, cornExplanation
Starch is found in plants such as potatoes, rice, wheat, and corn. These plants store starch as a reserve energy source in their cells. Starch is a complex carbohydrate made up of long chains of glucose molecules. It serves as a crucial source of energy for both plants and animals. In plants, starch is typically found in storage organs like tubers (potatoes), grains (rice, wheat), and seeds (corn). These plant sources are commonly consumed by humans and used as staple foods due to their high starch content.Rate this question:
- 23.
What must the body do first to use complex carbohydrates, starch, in order for it to burn as energy?
Correct Answer
break it down
make it smaller
turn it into smaller molecules'Explanation
To use complex carbohydrates, starch, as energy, the body must first break it down into smaller molecules. This process is known as digestion and occurs in the digestive system. The body breaks down complex carbohydrates into simpler sugars, such as glucose, which can then be absorbed into the bloodstream and used as fuel by cells for energy production. By breaking down complex carbohydrates into smaller molecules, the body can efficiently extract and utilize the energy stored in them.Rate this question:
- 24.
What does fiber have in common with starch
Correct Answer
they are both complex carbohydratesExplanation
Fiber and starch have a common characteristic of being complex carbohydrates. Complex carbohydrates are made up of long chains of sugar molecules. Both fiber and starch are types of complex carbohydrates that provide energy to the body. However, they differ in terms of their digestibility. Starch is easily broken down by the body into glucose for energy, while fiber cannot be fully digested and adds bulk to the diet, aiding in digestion and promoting bowel regularity.Rate this question:
- 25.
What is different about fiber?
Correct Answer
it cannot be broken down
fiber passes through the body and is eliminated
it is not considered a nutrientExplanation
Fiber is different from other substances because it cannot be broken down by the body's digestive enzymes. Instead, it passes through the digestive system without being absorbed or providing any calories. This indigestible nature of fiber allows it to add bulk to the stool and promote regular bowel movements. Additionally, fiber is not considered a nutrient because it does not provide any essential nutrients like carbohydrates, proteins, or fats. However, it plays a crucial role in maintaining digestive health and preventing certain diseases.Rate this question:
- 26.
Nutritions recommend that blank to blank percent of the Calories in a diet come from carbs.(include the to in your answer)
Correct Answer
45 to 65Explanation
Nutrition experts recommend that 45 to 65 percent of the calories in a diet should come from carbohydrates. This range ensures an adequate intake of energy and nutrients from carbohydrates, which are the body's main source of fuel. Carbohydrates provide essential nutrients, such as fiber, vitamins, and minerals, and they are important for maintaining optimal health and energy levels. By consuming carbohydrates within this recommended range, individuals can achieve a balanced and nutritious diet.Rate this question:
