Answer 1

Answer 1:correct option is phospholipid.

This  lipid is major component in cell membrane is phospholipid .Cell membrane is made of lipid bilayer which is arranged in two layers of phospholipids.A phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group.Steroid and,triglyceride are not major lipid in plasma membrane. Hydrocarbons are not lipids. So correct option is phospholipid.

Answer 2:Building blocks of protein is amino acid. Proteins are the polymer of amino acids which are connected via peptide bond.All other options are not correct.

Answer 3: Energy storage is not the function of protien. Energy is stored in the form of ATP. ATP is made up of of adenosine (an adenine ring and a ribose sugar) – and three phosphate groups (triphosphate).Hemoglobin(metalloprotien),digestive enzymes and keratin in hair are the protien.

Answer 4: correct option is True.

Molecules forming a hydrogen bond with the water molecule are said to be hydrophilic. So hydrophilic molecules will easily form hydrogen bond with water.

Answer 5: The nucleolus makes ribosomal subunits from proteins and ribosomal RNA.Thus nucleolus of nucleus is the site of ribosomal subunits manufacturing.

All other options are not correct.

Answer 6: The ‘shipping department’ of eukaryotic cells called the golgi apparatus can collect, package, modify, and transport molecules.All other options are not correct.

Answer 7:Ribosomes carry out protien synthesis.The endoplasmic reticulum (ER) is the main site for lipid synthesis. ATP is produced in mitochondria. Peroxisome help eliminate toxins in the liver. So correct option is carry out protien synthesis by ribosomes.

Answer 8: Ribosomes are not attached to smooth endoplasmic reticulum. When ribosomes are attached to endoplasmic reticulum then it is called rough endoplasmic reticulum. Smooth endoplasmic reticulum is a site of calcium storage, detoxification of foreign substance and site of membrane lipid synthesis.so all statements are true regarding Smooth endoplasmic reticulum except attached ribosome.

Answer 9 : Lysosomes are found in animal cell only that can digest nutrients and can prevent the build up of cellular waste which can lead to disease.So all statements applies for lysosome except for third which is lysosome found only in plants.

Answer 10: ATP is the nucleic acid energy molecule that is produced in the mitochondrion. DNA ,RNA are not energy molecule. Glucose is not nucleic acid energy molecule. So correct option is (i). ATP
