Question

name(s):
photosynthesis and respiration model
essential question: what is the relationship between photosynthesis and respiration?
scientific modeling is an activity that aims to make the world easier to understand. there are many types of models, some are mathematical, and some are graphical models that help us visualize the subject. the graphic below is a model that attempts to show the interdependence of two cellular processes: respiration and photosynthesis.
your goal is to examine the model, focus on the key details to answer the essential question.
sunlight (energy)
photosynthesis:
6co₂ + 6h₂o + energy → c₆h₁₂o₆ + 6o₂
chloroplast
co₂ + h₂o
glucose
mitochondrion
energy (atp)
respiration:
c₆h₁₂o₆ + 6o₂ → 6co₂ + 6h₂o + energy

Explanation:

Photosynthesis uses \(CO_2\), \(H_2O\), and sunlight (energy) to produce glucose (\(C_6H_{12}O_6\)) and \(O_2\). Respiration uses glucose (\(C_6H_{12}O_6\)) and \(O_2\) to produce \(CO_2\), \(H_2O\), and energy (ATP). The products of photosynthesis (\(C_6H_{12}O_6\) and \(O_2\)) are the reactants for respiration. The products of respiration (\(CO_2\) and \(H_2O\)) are the reactants for photosynthesis. So they are interdependent.

Answer:

Photosynthesis and respiration are interdependent. The products of photosynthesis (\(C_6H_{12}O_6\) and \(O_2\)) are the reactants for respiration. The products of respiration (\(CO_2\) and \(H_2O\)) are the reactants for photosynthesis.
