Educational worksheet for learning cellular respiration, featuring a diagram and questions to complete the chemical equation and understand the process.

Let's solve the Cellular Respiration Worksheet step by step and explain each part clearly.

Question 1: Complete the equation for cellular respiration

The balanced chemical equation for cellular respiration is:

> C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy (ATP)

We are given a diagram with boxes to fill in both symbols and names, along with labels like "Reactants" and "Products".

#### Step-by-step filling:

Top row (symbols):
- First box: C₆H₁₂O₆ (glucose)
- Second box: O₂ (oxygen gas)
- Arrow points to:
- First product: CO₂ (carbon dioxide)
- Second product: H₂O (water)
- Third product: ATP (useable energy)

But note: The worksheet shows 6 in front of O₂, CO₂, and H₂O — so we must include those coefficients.

So the top row becomes:
```
[ C₆H₁₂O₆ ] + [ 6 ] [ O₂ ] → [ 6 ] [ CO₂ ] + [ 6 ] [ H₂O ] + [ ATP ]
```

Now, below each symbol, write the name of the chemical:

- C₆H₁₂O₆ → Glucose
- O₂ → Oxygen Gas
- CO₂ → Carbon Dioxide
- H₂O → Water
- ATP → Useable Energy

Then, label the reactants (on the left) and products (on the right):

- Reactants: Glucose and Oxygen Gas
- Products: Carbon Dioxide, Water, Useable Energy

Now let’s fill in the diagram accordingly.

#### Final Answer for Question 1:

Top Row (Symbols):
- Box 1: C₆H₁₂O₆
- Box 2: O₂
- Product 1: CO₂
- Product 2: H₂O
- Product 3: ATP

Second Row (Names):
- C₆H₁₂O₆ → Glucose
- O₂ → Oxygen Gas
- CO₂ → Carbon Dioxide
- H₂O → Water
- ATP → Useable Energy

Bottom Labels:
- Left side (reactants): Reactants
- Right side (products): Products

✔ So the completed diagram should show:
```
[ C₆H₁₂O₆ ] + [ 6 ] [ O₂ ] → [ 6 ] [ CO₂ ] + [ 6 ] [ H₂O ] + [ ATP ]

Question 2: Link between Photosynthesis and Cellular Respiration

Fill in the blanks:

> In a plant, before it can do cellular respiration it must make food. To do this it needs carbon dioxide from the air, water from the soil, and sunlight. The food it produces is glucose. With the glucose from photosynthesis, it can then go through cellular respiration. Glucose (the food) and oxygen from the air combine in cellular respiration. They form carbon dioxide (which is a gas), water, and ATP (which provides energy). The purpose of cellular respiration is to make ATP and carbon dioxide and water are waste products that are let go in the process.

---

#### Explanation:
- Photosynthesis: Plants use CO₂, H₂O, and sunlight to make glucose.
- Cellular Respiration: Glucose and O₂ are used to produce ATP (energy), with CO₂ and H₂O as waste.
- So, the products of photosynthesis (glucose and oxygen) are reactants in cellular respiration.

Question 3: Fill in the blanks with correct words

This seems to be a drag-and-drop activity on an online worksheet (LiveWorksheets). Since the image doesn’t show the exact blank spaces or word bank, but based on context, the likely words to be dragged are:

- Glucose
- Oxygen
- Carbon Dioxide
- Water
- ATP
- Useable Energy
- Reactants
- Products

These would be placed into sentences or diagrams depending on the format.

But since no specific sentence is shown in your image for Q3, and it says “drag and drop,” you’d match these terms to their correct positions in a diagram or sentence.
