Biology Questions

Cellular respiration is the multi-step process that creates energy from nutrients and food molecules. It begins in the cytoplasm of the cell, with the mitochondria functioning as the main organelle where the rest of the process continues and finishes.

During respiration, glycolysis occurs in the cytoplasm of the cell.

Ribosomes comprise a complex macro molecular machine, found within all living cells, that serves as the site of biological protein synthesis. Ribosomes link amino acids together in the order specified by messenger RNA molecules.

We know that, when we eat a meal, any carbohydrates we've eaten are broken down into glucose and passed into the bloodstream. This rise in blood glucose causes insulin to be released from the pancreas so glucose can move inside the cells and be used. As glucose moves inside the cells, the amount of glucose in the bloodstream returns to normal and insulin release slows down.

When a cell undergoes meiosis process, it produces 4 haploid cells as a result.

A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.

Most cellular activities will occur in the cytoplasm of the cell. Many metabolic pathways including glycolysis and process such as cell division occurs in the cytoplasm of the cell.

A nucleotide is an organic molecule that is the building block of DNA and RNA. They also have functions related to cell signaling, metabolism, and enzyme reactions. A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine. RNA contains uracil, instead of thymine. 

A nucleotide within a chain makes up the genetic material of all known living things.
