Enzymes that drive metabolism and antibodies of the immune system are both

forms of
A. minerals. C. lipids.
B. proteins. D. carbohydrates.

(C) I can't find the answer in my book, would you plz help me?

Check this site.

I checked the site and from what I read I now think the answer is (B) is this correct?

proteins

Of course, I'd be happy to help you find the answer. To determine which option is correct, we can break down the question and analyze the characteristics of both enzymes and antibodies.

Enzymes are biological molecules that act as catalysts, meaning they speed up chemical reactions in the body. They are involved in various metabolic processes and are essential for maintaining normal bodily functions.

Antibodies, on the other hand, are part of the immune system's defense mechanism. They are proteins produced by specialized cells in response to the presence of foreign substances (such as pathogens or toxins) in the body. Antibodies help the immune system identify and neutralize these foreign substances.

Now let's look at the answer choices:

A. Minerals: Enzymes and antibodies are not minerals. Minerals are inorganic substances that are necessary for physiological functions, but they are not directly involved in the metabolic or immune systems.

B. Proteins: Enzymes and antibodies are both proteins. Proteins are large, complex molecules that have a wide range of functions in living organisms, including the catalytic activity of enzymes and the immune response mediated by antibodies. This makes option B a plausible choice.

C. Lipids: Enzymes and antibodies are not lipids. Lipids are a group of organic compounds that include fats, oils, and waxes. They play roles in energy storage, insulation, and cell membrane structure, but are not directly involved in metabolic processes or the immune system.

D. Carbohydrates: Enzymes and antibodies are also not carbohydrates. Carbohydrates are another group of organic compounds that serve as a source of energy for the body and play roles in structural support (such as in cell walls). They are not primarily involved in enzymatic reactions or immune response.

Based on this analysis, we can conclude that the correct answer is B. Proteins. Both enzymes and antibodies are forms of proteins that play important roles in metabolism and immune response, respectively.
