Why are antacids an effective treatment for excess stomach acid? A. Antacids degrade acids B. Antacids release water, which dilutes the stomach acid C. Antacids prevent HCI in the stomach from splitting into H+ and CH D. Antacids are basic, and they neutralize stomach acid. What is the primary role of carbohydrates in living organisms? fuel for cellular mechanisms B. speeding up chemical reactions C. storing information D. structural materials is the most important monosaccharide for living organisms. B. Fructose C. Sucrose D. Glucose E. Lactose All lipids ares Al used for short-term energy storage. B. nonpolar and insoluble in water. C. modified forms of cholesterol. DI phospholipids that form cell membranes Which of the following is not a function of proteins? A. help fight invading microorganisms in the body Iform the membrane that surrounds the contents of cells control cell activity in the body D. transport molecules, such as oxygen, around the body Your body can manufacture certain amino acids as they are needed, others must come from your diet. The amino acids that come from your diet are known as: primary amino acids! carboxyl amino acids essential amino acids! plant amino acids

Answer 1. Option B. Antacids are basic and they neutralize stomach acids

Answer 2. Option A. Fuel for cellular mechanism

Answer 3. Option D. Glucose

Answer 4. Option B. Are non polar and insoluble in water

Answer 5. Option C. Controls cell activity in the body

Answer 6. Option C. Essential amino acids

Ans 1 . Explanation:

Acidity in the stomach is due to the excess of acid hence to neutralize this acidity a base/ alkaline substance is required. Antacids are basic in nature and thus helps to neutralize the acid in the stomach

Ans 2. Explanation:

Carbohydrates are one of the nutrients required for the body for many purposes. It is a biomolecule made up of carbon, hydrogen and oxygen. There are many functions of carbohydrates in our body but the most important function is to provide energy or fuel for cellular mechanism. Apart from this other functions include synthesis of macro-molecules, stored for future uses etc.

Ans 3. The most important monosaccharide for living organism is Glucose because it is the source of energy for cells and organs.

Ans 4. All lipids are non polar and insoluble in water because they have a hydrophobic non polar group.

Option A is incorrect because they are not short term energy source but long term energy source. Carbohydrates are the short term energy source.

Option C is incorrect because all lipids are not cholesterol. In fact all cholesterol are lipids.

Option D is also incorrect because all lipids are not phospholipids. Phospholipids are a type of lipids.

Ans 5. Proteins have may important role in our body like

a. They functions as antibodies thus fighting against invading microorganism

b. They form a part of cell membranes

c. Hemoglobin is a protein which helps in the transport of oxygen through out the body.

Hence the answer for the question is Option C, proteins do not control the cell activity in the body. Cell activities are controlled by the DNA in the nucleus which are polynucleotide.

Ans 6. Amino acids are divided into 2 based on their requirement by the body. They are essential amino acids are non essential amino acids, Amino acids that can be produced by the body and need not be supplied from outside are called non essential amino acids where as the amino acids that cannot be synthesized in the body and need to be provided in the food are called essential amino acids. Hence the answer is option C. Essential amino acids.
