Why do cells need to carry out cellular respiration and protein synthesis?

How does a cell know that its neighbors are the correct ones and that, if not, it should move or kill itself?

Imagine that you are given an unknown cell sample. You visualize the sample under the microscope and you notice that it has a large number of mitochondria. Based on this observation, what can you say about the function of this cell? The cell might be storing a large amount of toxins. The cell might engulf and digest a large amount of material. The cell might require large amounts of energy. The cell might degrade large amounts of fatty acids.

What are five safety mechanisms that regulate cell growth and division?

Which of the following proteins does not function in cell-cell interaction? a) Cadherin b) Cytochrome c c) Integrin d) N-CAM

Imagine you are working in a lab and you examine an unknown cell only to discover it possesses gap junctions and microvilli. Based on those findings, what can you assume regarding its function(s)? O a) it specializes in intercellular communication O b) it can withstand mechanical stress c) it likely functions in absorption O d) A and C O e) B and C

Why can mitochondria be considered the "power plants" of aerobic cells?

Which of the following BEST represents the function of DNA in a cell? A) to provide structure and support to the cell B) to store genetic information C) to speed up the rate of reactions in the cell D) to digest macronutrients in the cell’s cytoplasm

What is the function of DNA? A) Stores chemically coded, heritable information in an organism B) Transfers genetic information from the nucleus to the cytoplasm C) Activates enzymes from inactive states under specific conditions D) Lowers the activation energy of important chemical reactions E) Serves as a barrier to the environment in the cell membrane

How can cells function differently even though they have the same DNA? What happens within the cell that causes it to take on different functions?
