Terms in this set (10) A major reason why people must have sufficient carbohydrate and fat in the diet is to: a.
prevent the loss of essential fatty acids
.
What happens when the diet is lacking an essential amino acid?
Amino acid deficiency can result in
decreased immunity, digestive problems, depression, fertility issues, lower mental alertness, slowed growth in children, and many other health issues
.
What is the process of breaking down proteins called?
Protein catabolism
is the process by which proteins are broken down to their amino acids. This is also called proteolysis and can be followed by further amino acid degradation.
Which minerals are most likely to be lacking in the diets of vegans?
- Vitamin B12. This particular vitamin is created by a bacteria and found primarily in animal products such as dairy, meat, insects, and eggs. …
- Vitamin D. Vitamin D is the sunshine vitamin! …
- Omega-3 Fatty Acids. …
- Zinc. …
- Iron.
Why are carbohydrates proteins and fats important?
Carbohydrates, proteins, and fats are the main types of macronutrients in food (nutrients that are required daily in large quantities).
They supply 90% of the dry weight of the diet and 100% of its energy
.
Why is it important to have a proper diet and nutrition?
A healthy diet is essential for good health and nutrition.
It protects you against many chronic noncommunicable diseases, such as heart disease, diabetes and cancer
. Eating a variety of foods and consuming less salt, sugars and saturated and industrially-produced trans-fats, are essential for healthy diet.
What would happen if the diet lacks an essential amino acid quizlet?
Eating only plant foods will not provide enough protein to meet daily needs. When there is a great shortage of amino acids,
the body must break down such tissues as blood, muscle, and skin
.
Why is it important that a protein keeps its shape?
The shape of a protein is critical to its function because
it determines whether the protein can interact with other molecules
.
Why are proteins so important to living organisms?
Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are
required for the structure, function, and regulation of the body's tissues and organs
.
Why is it necessary to break down proteins in the digestive system?
Then protease enzymes in your stomach break down the proteins that will
build new cells and repair damaged tissue
. Stomach acid helps protease enzymes to destroy harmful microorganisms that may be present in the food. Fats and oils, or lipids, provide insulation and an energy store for our bodies.
How do carbohydrates proteins and fats get digested in human being?
Carbohydrates, proteins, and fats are digested
in the intestine
, where they are broken down into their basic units: Carbohydrates into sugars. Proteins into amino acids. Fats into fatty acids and glycerol.
Do you need fat to digest protein?
Since the process of making the enzymes and other proteins requires energy, this protein building may be compromised if you do not have enough available energy.
Fat is essential for making some hormones, composing proper cell membrane structures and absorbing fat-soluble vitamins.
When following a normal diet a person should get what percent of their calories from carbohydrates?
Adults should get
45 percent to 65 percent
of their calories from carbohydrates, 20 percent to 35 percent from fat, and 10 to 35 percent from protein.
What is the main nutrition-related problem likely to be encountered by a vegan if his or her diet is not carefully selected?
Insufficient intake of Vitamin B
-12.
What can't vegans eat?
- Beef, pork, lamb, and other red meat.
- Chicken, duck, and other poultry.
- Fish or shellfish such as crabs, clams, and mussels.
- Eggs.
- Cheese, butter.
- Milk, cream, ice cream, and other dairy products.
- Mayonnaise (because it includes egg yolks)
- Honey.
Why is carbohydrate intake is important especially for athletes?
Carbohydrates
provide energy for the body including our muscles, brain, nerves and other body tissues
. Anytime we are performing an activity in which we need a lot of energy and fast, such as resistance training and carrying bags of mulch, carbohydrates are the predominant energy source during those activities.
Why is carbohydrate intake important?
Carbohydrates are essential for a well-balanced diet and healthy body.
They are the body's preferred energy source and fuel vital organs – including the brain, central nervous system and kidneys
. Carbohydrate is also an important energy source during exercise.
Why is carbohydrate important?
The most common and abundant forms are sugars, fibers, and starches. Foods high in carbohydrates are an important part of a healthy diet. Carbohydrates
provide the body with glucose, which is converted to energy used to support bodily functions and physical activity
.
Which amino acid is not essential amino acids?
Nonessential amino acids include:
alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine
. Conditional amino acids are usually not essential, except in times of illness and stress.
Which combination of foods would not provide all the essential amino acids?
Examples include such foods as meat, eggs, milk, and soybeans. Incomplete protein foods such as
beans and peas
do not contain all of the essential amino acids and must be combined in one meal with other foods or one another to supply all nine essential amino acids.
Can amino acids make glucose?
A glucogenic amino acid (or glucoplastic amino acid) is an amino acid that can be converted into glucose through gluconeogenesis
. This is in contrast to the ketogenic amino acids, which are converted into ketone bodies.
Why is shape and structure so important to enzyme function?
Why is shape important? The shape of an enzyme is very important because
it has a direct effect on how it catalyzes a reaction
. An enzyme's shape is determined by the sequence of amino acids in its structure, and the bonds which form between the atoms of those molecules.
What is responsible for specifying the 3d shape of a protein?
Explanation:
The amino acid sequence
of a protein determines its three-dimensional shape.
What is responsible for holding the shape of a protein?
The primary structure of a protein — its
amino acid sequence
— drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape.
