Answer:

a. glycolysis—preparatory reaction--cirtric acid cycle--electron transport system

Explanation:

Glycolysis is the first stage of cellular respiration that occurs in the cytoplasm of the cell. During glycolysis one 6 carbon glucose is converted into two molecules of 3 carbon pyruvic acid or pyruvate.
In the preparatory reaction, the pyruvate converted into a two-carbon molecule called acetyl CoA. In this reaction, a carbon dioxide molecule is released and a molecule of NADH is released.
The citric acid cycle begins with the reaction of the acetyl CoA with a four-carbon molecule in the mitochondrisl matrix. It goes through a cycle of reactions regenerating the four-carbon starting molecule. ATP, NADH and FADH₂ are produced.
The electron transport system is the terminal step of aerobic respiration that operates on the inner membrane of the mitochondria. Reduced coenzymes NADH and FADH₂ move along electron transport system release high-energy electrons and produce ATP.

Based on what you know about the six types of infectious agents, what type of agent do you think was plaguing Anna explain your

AleksAgata [21]

Infectious agents are those that corrupt and prey on an organism or a host. This is sometimes called parasitism when a foreign organism consumes a host by preying on its nutrients and food. Hence, we are uncertain in Anna's case because there is no clear description of her symptoms.

Energy is the ability to do work which is stored in the body inform of ATP (adenosine triphosphate). ATP is comprised of a base Adenine, a ribose sugar (5 carbon sugar) and three phosphate groups. when a bond is broken energy is released and when a bond is formed energy is stored. ATP is used by cells as a source of energy such that ATP can easily release or store energy by breaking the chemical bonds and reforming the bonds between its phosphate group. The correct answer is c, phosphate- phosphate bond
