Answer
Respiration
Respiration is a vital process in cells that breaks down glucose to produce energy (ATP), carbon dioxide, and water. It involves two main steps: glycolysis in the cytoplasm and the Krebs cycle and electron transport chain in the mitochondria. Oxygen is essential for this process. Without respiration, cells cannot produce the energy needed to function, making it crucial for life.
Questions:
-
Processes in Organisms Labeled 3:
- Krebs Cycle (Citric Acid Cycle)
- Electron Transport Chain
-
Processes in Organisms Labeled 2:
- Glycolysis
- Fermentation (if oxygen is absent)
-
Word Equation for Question 1:
Glucose + Oxygen → Carbon Dioxide + Water + Energy (ATP) -
Arrow in Word Equation:
Indicates the direction of the chemical reaction from reactants to products. -
Substances and Their Sources:
- Glucose: From dietary carbohydrates, absorbed into cells.
- Oxygen: From the air, transported to cells via the bloodstream.
-
Products and Their Destinations:
- Carbon Dioxide: Expelled from the body during exhalation.
- Water: Used or excreted by the body.
- Energy (ATP): Used to power cellular activities.
-
Importance of Respiration for Life:
Provides the energy needed for all cellular functions, maintaining life processes.
Summary:
Respiration is essential for producing energy in cells, enabling vital functions and sustaining life.

The Deep Dive
Respiration is a fascinating process that happens in all living organisms, acting as their energy engine! In the cells marked as 3, cellular respiration occurs, where glucose and oxygen are converted into carbon dioxide, water, and energy in the form of ATP—a supercharged battery for cells. Meanwhile, in the cells marked as 2, fermentation and anaerobic respiration can take place, especially in low-oxygen environments, allowing some organisms to still generate energy.
The word equation for cellular respiration is: Glucose + Oxygen → Carbon Dioxide + Water + Energy (ATP). The arrow in this equation shows the transformation of reactants into products, indicating the directional flow of the reaction. Glucose typically comes from the food we consume, while oxygen is absorbed from the air. In turn, glucose is broken down to release energy, while carbon dioxide and water are by-products, which are expelled from the body. This process is crucial as it provides energy necessary for growth, repair, and maintenance of all life functions!
