Which cell structure is associated with the breakdown of harmful substances?
Lysosomes
Lysosomes break down harmful cell products, waste materials, and cellular debris and then force them out of the cell. They also digest invading organisms such as bacteria.
Which one of the following cell structures is associated with the breakdown of harmful substances or substances that are no longer needed by the cell?
Which of the following cell structures is associated with the breakdown of harmful substances or substances that are no longer needed by the cell? The plasma cell produces thousands of antibodies per second.
Can all cells Interconvert chemical materials?
A) All cells can interconvert forms of energy. All cells have a cell wall.
What cell structure makes hexokinase?
What cellular structure makes hexokinase? An immune system cell called the plasma cell produces thousands of antibodies (a type of protein) per second for release into the body.
What destroys harmful substances or worn?
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.

What cells lack a membrane enclosed nucleus?
Prokaryotic Cell: A type of cell lacking a membrane-enclosed nucleus and membrane-enclosed organelles; found only in the domains Bacteria and Archaea.
What is the complex of proteins and DNA in a nondividing cell is called?
Chromatin. The complex of proteins and DNA in a nondividing cell.
What is glucokinase and hexokinase?
Glucokinase and Hexokinase are enzymes which phosphorylate glucose to glucose-6-phosphate, trapping glucose inside the cell. Glucokinase is present in hepatocytes of the liver and beta cells of pancreas, tissues that needs to quickly respond to changes in glucose levels. Hexokinase is found in most tissues.
Which is statement about cellular metabolism is false?
Are hydrophobic and face outward towards the aqueous solution on both sides of the membrane Which of the following statements about cellular metabolism is false? A woman is having trouble becoming pregnant. Examination of her partner’s sperm indicates that dynein feet are missing from the flagella in his sperm cells.
Why does a problem present no problem to the cell?
A. Should present no problem to the cell, because the surface area of the cell will increase as the volume of the cell increases B. Should present no problem to the cell, since it can continue to perform all other necessary functions C.
Which is a false statement about the cytoskeleton?
Which of the following statements about the cytoskeleton is false? A. Once laid down, the elements of the cytoskeleton are fixed and remain permanently in place B. The cytoskeleton plays an important role in amoeboid motion C. The cytoskeleton is composed of three types of fibers: Microflaments, microtubules, and intermediate flaments D.
Which is location in a cell is unlikely to contain ribosomes?
C. All cells have cell walls D. All cells are motile A. Is due to the absence of an enzyme that digests polysaccharides Which location in the cell is unlikely to contain ribosomes or ribosomal subunits? A. Are found only in plants, whereas microtubules are found in both plants and animal cells B. Are thicker than microtubules D.
