Question

carbohydrates are important nutrients that supply energy for pretty much everything that happens in our cells. our bodies break down larger carbohydrates into the sugar glucose, which is used to power our muscles, nervous systems, and more. to the right is a graph of what happens to glucose as our bodies break it down for energy.
which molecules are present, increasing, decreasing, or staying constant in the graph to the right?
carbon dioxide (co₂)
nitrous oxide (no)
glucose (c₆h₁₂o₆)
nitrogen gas (n₂)
water vapor (h₂o)
oxygen (o₂)
id like to review how to read graphs.
why do the lines on my graph look jagged?

Explanation:

• Carbon dioxide ($CO_2$): Present and increasing. As glucose is broken down, carbon dioxide is a product of the metabolic process, so its concentration rises over time.
• Nitrous oxide ($NO$): Not present. There is no indication in the graph or the context of glucose breakdown (which is related to cellular respiration, not a process that typically involves nitrous oxide production in this context) that this molecule is involved.
• Glucose ($C_6H_{12}O_6$): Present and decreasing. The body breaks down glucose for energy, so its concentration in the system (as per the graph) goes down over time.
• Nitrogen gas ($N_2$): Not present. Nitrogen gas is not directly involved in the glucose - breakdown (cellular respiration) process shown in the graph.
• Water vapor ($H_2O$): Present and increasing. Water is also a product of cellular respiration (when glucose is broken down in the presence of oxygen), so its concentration increases.
• Oxygen ($O_2$): Present and decreasing. Oxygen is consumed in the process of breaking down glucose (cellular respiration: $C_6H_{12}O_6+6O_2

ightarrow6CO_2 + 6H_2O$), so its concentration decreases.

Answer:

Carbon dioxide ($CO_2$): Present, increasing.
Nitrous oxide ($NO$): Not present.
Glucose ($C_6H_{12}O_6$): Present, decreasing.
Nitrogen gas ($N_2$): Not present.
Water vapor ($H_2O$): Present, increasing.
Oxygen ($O_2$): Present, decreasing.
