Unit 5 - Cell Energy

Let's start with a review of photosynthesis

Multiple Select

What are THREE things that plants need in order to do photosynthesis?

• Carbon dioxide

• Glucose

• Light energy

• Oxygen

• Water

Multiple Select

What are TWO things that plants MAKE through photosynthesis?

• Carbon dioxide

• Glucose

• Light energy

• Oxygen

• Water

Multiple Choice

Which of the following is the ENERGY MOLECULE that plants make through photosynthesis?

• Carbon dioxide

• Glucose

• Light energy

• Oxygen

• Water

Photosynthesis Recap

• The main purpose of photosynthesis is for plants to convert LIGHT energy into CHEMICAL energy

• This chemical energy is GLUCOSE (sugar)

• Glucose is stored in plants. When you eat plants, you get glucose!

The Problem

• Glucose is great for storing energy, but it's TOO BIG for quick cell jobs

• This is like using a $50 in a vending machine to buy a $1 snack and not getting $49 back in change

• How do we turn GLUCOSE into SMALLER energy molecules?

A process called CELLULAR RESPIRATION is the solution!

Multiple Choice

In which cell organelle does cellular respiration take place?

• Chloroplast

• Endoplasmic reticulum

• Mitochondria

• Nucleus

Multiple Choice

What types of organisms can do cellular respiration?

• Animals only

• Plants only

• Animals and Plants

Multiple Select

What are the TWO REACTANTS of cellular respiration? (things that the reaction NEEDS)

• ATP Energy

• Carbon dioxide (CO2)

• Glucose (C6H12O6)

• Oxygen (O2)

• Water (H2O)

Multiple Select

What are the THREE PRODUCTS of cellular respiration? (things that the reaction MAKES)

• ATP Energy

• Carbon dioxide (CO2)

• Glucose (C6H12O6)

• Oxygen (O2)

• Water (H2O)

Fill in the Blanks

How many ATP energy molecules does 1 molecule of glucose make?

Photosynthesis and Cellular Respiration are a CYCLE

• Notice that some molecules are constantly recycled between the two processes

• What photosynthesis makes, cellular respiration needs

• Let's compare the two processes

Multiple Select

Photosynthesis makes ___ and ___, which cellular respiration needs. Choose TWO correct answers.

• ATP energy

• Carbon dioxide

• Glucose

• Light energy

• Oxygen

Multiple Choice

Photosynthesis makes ___ energy, which cellular respiration breaks down to make ___ energy.

• Glucose , ATP

• ATP , Glucose

Multiple Choice

What gas does photosynthesis release into the atmosphere that is required for cellular respiration? You breathe this gas :)

• Carbon dioxide (CO2)

• Oxygen (O2)

• Water (H2O)

Multiple Select

Cellular respiration releases TWO byproducts that are recycled and reused by photosynthesis.

• Carbon dioxide (CO2)

• Glucose (C6H12O6)

• Oxygen (O2)

• Water (H2O)

Multiple Choice

Photosynthesis occurs in the organelle called the ___ , and cellular respiration occurs in the organelle called the ___.

• Chloroplast , Mitochondria

• Mitochondria , Chloroplast

Multiple Choice

___ can do photosynthesis, and ___ can do cellular respiration.

• Only plants , only animals

• Only plants , both plants and animals

• Only animals , only plants

• Both plants and animals , only plants
