Photosynthesis In-Depth

Photosynthesis In-Depth

By Justin Tice

• The process of converting light energy into sugars (glucose) that store chemical energy​

• Happens in the leaves of plants inside of chloroplasts​

• 3-part process​

​Photosynthesis

Multiple Choice

Where does photosynthesis occur?

• Mitochondria

• Chloroplast

• Ribosome

• Nucleus

• ​Grana

• Stroma​

​Chloroplasts

​Two Main Parts

​

Multiple Select

What are the two main parts of the chloroplasts? (multiple answers)

• Grana

• Mitochondria

• Stroma

• Lamella

• Stacks of thylakoids are called Grana

• Thylakoids contain the chlorophyll​

• Location of the light-dependent reactions​

​

​Grana

​

Multiple Choice

What are the coin-shaped membrane enclosed compartments that make up the Grana called?

• Mitochondria

• Chloroplasts

• Thylakoids

• Chlorophyll

• Fluid that surrounds the grana inside a chloroplast

• ​Location of the light-independent reactions

​

​Stroma

• Photosystem II

• Photosystem I

• ​Calvin Cycle

​

​3 part process

Multiple Select

Which of these processes are light-dependent reactions?

• Photosystem I

• Photosystem II

• Calvin Cycle

• Krebs Cycle

Multiple Choice

Which of these processes are light-independent reactions?

• Photosystem I

• Photosystem II

• Calvin Cycle

• Krebs Cycle

• Photosystem II

• Photosystem I​​

​

​Light-Dependent Reactions

​

• Energy absorbed from sunlight by the chloroplasts

• H₂O molecules broken via enzymes

• H⁺ ions pumped into the thylakoid

​

​Photosystem II

• Energy absorbed f​rom sunlight

• NADPH produced

• Hydrogen Ion Diffuse out of Thylakoid

• ATP produced​ via hydrogen ions flowing through ATP synthase​

​

​Photosystem I

• The Calvin Cycle

• Occur in the stroma​

• Use ATP and NADPH from the light-dependent reactions

• Makes Glucose​

​

​Some text here about the topic of discussion.

​Light-independent Reactions

​

• CO²​ added to a 5-C molecule creating a 6-C molecule

• ​Two 3-C molecules formed by splitting the 6-C molecule

• ​1 3-C molecule exits then is bonded to another creating Glucose

• The other 3-C molecule is recycled back into a 5-C molecule then used in step 1​

​

​Calvin Cycle

Multiple Choice

Where do the 5-Carbon molecules in step 1 come from?

• The atmosphere

• Recycled from step 4

• Soil

• Broccoli
