Question

Biochemistry 2 antibodies to defend the cell against “invaders” . can be utilized for energy if sugars are not available . DNA or RNA . Forms the hydroponic part of the plasma membrane . Glucose and sucrose starches and sugar: answers choices: carbohydrates, Lipid , Protein, nucleic acid

Answer 1

Ans.

-Antibodies are components of adaptive immune system that target and neutralize pathogens, such as bacteria, and viruses or their components. Antibodies are protein molecules, made up of four polypeptide chains.

-In all organisms, usually sugars, such as glucose act as main source of energy. However, in the absence of sugars (during starvation period) stored fat or lipid molecules are utilized to generate energy.

-DNA or RNA are nucleic acid molecules, made up of nucleotide subunits. Each nucleotide is composed of a pentose sugar (in DNA, deoxyribose sugar, while in RNA, ribose sugar), a nitrogen base, and a molecule of phosphate.

-Carbohydrates are complex biomolecules, made up of hydrogen, carbon, and oxygen atoms. Glucose, sucrose, and starch are examples of carbohydrates.

Answer 2

Carbohydrate:

Starches and sugars

Glucose and sucrose

Lipid:

Forms the hydrophobic part of the plasma membrane

Can be utilized for energy if sugars are not available

Protein:

Antibodies to defend the cell against "invaders"

Nucleic Acid:

DNA or RNA

I did this thingy already these answers are 100% correct

hope this helps :)
