Answer:

Our digestive system has the ability to convert macromolecules into micromolecules.

Explanation:

Our digestive system has the ability to convert macromolecules into micromolecules with the help of certain enzymes. Carbohydrate is a macromolecule which is converted into glucose molecule with the help of saliva which is an enzyme present in the mouth, protein is also a macromolecule that is converted into amino acid so that our body cells can absorb it and fats are also macromolecules which can be converted into fatty acids with the help of digestive system. The cells produced waste materials such as carbondioxide gas and nitrogenous material which can be excreted through excretory system such as lungs and urinary bladder.

Answer:

1) In eukaryotic flagella, the fibers that slide past one another due to the activity of dynein proteins are microtubules.

2) Many cell organelles, most notably the nucleus, are anchored by intermediate filaments which are assembled from a diverse class of proteins.

3) Centrosomes are sites where protein dimers assemble into microtubules.

4) The extension of pseudopodia in amoeba is due to the regulated assembly and destruction of microfilaments.

5) The only cytoskeletal fibers not associated with intracellular movement or whole cell locomotion are the intermediate filaments.

6) During muscle contractions, myosin motor proteins move across tracks of microfilaments.

Explanation:

The cytoskeleton is a very important element of the cell, and is composed of three different structures: microtubules, intermediate filaments, and microfilaments.

Microtubules are structures in the shape of hollow tubes that give shape to the cell. Microtubules also participate in cell motility by providing a route for the organelles to move through.

Intermediate filaments are the only ones that do not participate in cell motility: their main function is to provide mechanical support for the plasma membrane.

Microfilaments are a key component in cell motility, and also associate with myosin (a protein) to produce muscle contraction. Microfilaments also give the cell the ability to grow pseudopods.
