Answer:
During presentation of APC-bound antigen, macrophages and dendritic cells secrete the cytokine, interleukin-1, that activates T helper cells
Explanation:
Macrophages interact with T cells in order to generate T cell activation in target organs, and are themselves activated by inflammatory messenger molecules (cytokines) produced by the T cells.
Macrophages produce toxic chemicals, such as nitric oxide, that can kill surrounding cells.

Answer:
Differences: Size
Similarities: Organelles
Explanation:
The most important difference is size. The volume of a typical human cell is 4,000 times more than the volume of a typical bacterial cell. Today's bacterial cells are direct descendants of the prokaryotic cells found in rocks that were formed one billion years after Earth.
Organelles are the biggest difference between bacteria and cells that make up the human body. An organelle is a tiny cellular structure that performs specific functions within a cell. Organelles are embedded within the cytoplasm of eukaryotic and prokaryotic cells. In the more complex eukaryotic cells, organelles are often enclosed by their own membrane
Answer:
The correct option is B.<u> It was mostly incorporated into proteins that regulate and manage metabolic reactions.</u>
Explanation:
The results of the experiment showed that most of the radiolabeled amino acids were present in the mitochondria.
Amino acids can be described as organic compounds which build up the proteins. There are 20 different kinds of amino acids which make up different kinds of proteins, each specified to perform specific functions.
The results from the experiment prove that the radiolabeled amino acid is being used to make proteins that are necessary for metabolic reactions.

Answer:
d. In the first stage, macro-molecules are converted to monomers, and a small amount of ATP is produced.
e. In the second stage, monomers are broken down, and a small amount of ATP is produced.
c. In the third stage, fuel molecules are completely oxidized to CO2, and no ATP is produced.
Explanation:
When we take food a process starts which is called as cellular respiration. Through this process the food energy is converted into cellular energy which will further used by body. During all this process oxygen and glucose are converted into water and carbon dioxide and energy in this process is converted into ATP.
