Which of the following statements about proteins is false? A. Protein helps maintain and grow muscle. B. Protein promotes fat loss. C. Protein is made of amino acids. D. Protein has only one form called peptide. E. Protein is a nutrient found only in animal products that helps our muscles grow and repair them self.
If you are student and trying to figure out correct answer, we mentioned all the aspects below for you so you can pick true of false according to your knowledge.
A. Protein helps maintain and grow muscle
Protein is an essential nutrient that helps your body generate enzymes, produce hormones, support your immune system, and build and maintain tissues. When you are deficient in protein, your body begins to break down muscle tissue.
Protein supplements can help you meet your daily requirements and may even aid in muscle growth. However, if you already consume enough protein from your diet and exercise regularly, protein supplements will not help your muscles grow. To get the most benefit from protein supplements use them in conjunction with a healthy diet and regular strength-training exercises.
In order to ensure that you consume enough protein to help with muscle growth, the American College of Sports Medicine recommends consuming about 0.5 to 0.8 grams of protein per pound of body weight per day for people engaged in strength training programs. For example, a 180-pound person would need between 90 and 144 grams of protein per day.
You can find protein in all kinds of foods, including meat and fish, dairy products such as milk, cheese and yogurt, and eggs. Some plant sources of protein include legumes like lentils or chickpeas and soy products such as tofu or edamame beans. If you find it difficult to meet your daily requirements through diet
B. Protein promotes fat loss.
You don’t need to worry about eating too much protein, as long as you’re getting enough carbs and fat. In fact, it’s important to eat plenty of protein because it helps with muscle repair, supports a healthy metabolism and more.
Here are some of the benefits of eating high-quality protein:
It promotes fat loss. A study published in the American Journal of Clinical Nutrition found that replacing carbohydrates with meat or dairy products would reduce a person’s risk of obesity.
It helps build (and maintain) muscle mass. Eating protein preserves lean muscle mass, which is essential for a strong metabolism and for burning fat. Protein also helps keep your muscle cells healthy.
It strengthens bones and prevents osteoporosis. Protein keeps calcium in the body, so it can be used for bone formation and growth rather than excreted through urine.
It promotes satiety. Protein makes you feel full faster and longer than carbs or fat do, so you end up eating less throughout the day.
Protein has minimal effect on blood sugar levels because it doesn’t cause a large insulin response like carbohydrates do. Insulin is the hormone responsible for storing fat in the body, so having low levels decreases your chances of gaining weight.
C. Protein is made of amino acids.
Protein is made of amino acids. These amino acids can be divided into two groups: essential and non-essential amino acids. Essential amino acids are those that cannot be manufactured by the body, and must therefore be taken in from food. Non-essential amino acids are produced by the body, and are only needed in small amounts. A protein that contains all of the essential amino acids is called a high quality protein.
High quality proteins include eggs, milk, meat (beef, chicken, pork, etc.), fish and shellfish, soybean (tofu), peanut butter, cheeses, nuts and seeds. Most of these foods also contain saturated fat and cholesterol. Other sources of protein provide us with only non-essential amino acids or incomplete proteins such as beans and grains or peas and pasta or corn and corn tortillas.
The most important nutrient for growing children is protein because it provides the building blocks for growth – amino acids! And getting the proper amount of high quality protein is important for maintaining good health throughout life – for building and repairing muscle tissue (including heart muscle), making enzymes to help digest food, producing hormones and hemoglobin (which carries oxygen in our blood).
D. Protein has only one form called peptide.
Proteins are large molecules that contain carbon, hydrogen, oxygen and nitrogen atoms. They also have additional atoms such as sulfur and phosphorous. Proteins can be made up of one or more polypeptide chains. A protein is a polymer; its monomer is called amino acid.
Proteins are essential nutrients for the human body. They are one of the building blocks of body tissue, and can also serve as a fuel source. As a fuel, proteins provide as much energy density as carbohydrates:
- 4 kcal per gram; in contrast
- lipids provide 9 kcal per gram
The most important aspect and defining characteristic of protein from a nutritional standpoint is its amino acid composition. Proteins are polymer chains made of amino acids linked together by peptide bonds.
During human digestion, proteins are broken down in the stomach to smaller polypeptide chains via hydrochloric acid and protease actions. This is crucial for the absorption of the essential amino acids that cannot be biosynthesized by the body.
There are nine essential amino acids which humans must obtain from their diet in order to prevent protein-energy malnutrition and resulting death. They are phenylalanine, valine, threonine, tryptophan, methionine
E. Protein is a nutrient found only in animal products that helps our muscles grow and repair them self.
Proteins are naturally made up of amino acids – small molecules that can be linked together to form long chains. Your body needs these amino acids to produce proteins, and the specific order in which they’re arranged is what gives each protein its unique characteristics.
There are 21 different amino acids your body can use to make proteins, including nine it cannot produce on its own, called essential amino acids. These must come from the food you eat. There are also three types of amino acids: essential, non-essential and conditional.
The type of protein you get from different foods depends on its amino acid profile. Animal proteins contain all nine essential amino acids, so they’re considered complete proteins. Plant proteins tend to be incomplete, lacking one or more of the essential amino acids.
Usually, getting enough protein isn’t a problem for most people following a healthy diet because most foods contain at least some protein. For example, fruits and vegetables contain small amounts, while nuts, seeds and legumes have higher amounts.
Problems may arise when you’re restricting your intake of certain foods or following an ultra-low-carb diet like the keto diet. However, vegetarian and vegan diets can be perfectly healthy.
