What is the overview of photosynthesis?
Photosynthesis is a multi-step process that requires sunlight, carbon dioxide, and water as substrates. It produces oxygen and glyceraldehyde-3-phosphate (G3P or GA3P), simple carbohydrate molecules that are high in energy and can subsequently be converted into glucose, sucrose, or other sugar molecules.
Where does photosynthesis occur in the chloroplast?
Photosynthesis: The Basics Photosynthesis takes place inside the chloroplasts that sit in the mesophyll of the leaves. The thylakoids sit inside the chloroplast and they contain chlorophyll which absorbs the different colours of the light spectrum to create energy (Source: Biology: LibreTexts).
What is the role of NADP+ in photosynthesis?
NADP+ functions as a carrier to transfer high energy electrons from chlorophyll to other molecules.
What are the two stages of photosynthesis?\?
Photosynthesis in the leaves of plants involves many steps, but it can be divided into two stages: the light-dependent reactions and the Calvin cycle. The light-dependent reactions take place in the thylakoid membrane and require a continuous supply of light energy.
What are the two main stages of photosynthesis?
There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle. Requires sunlight? Schematic of the light-dependent reactions and Calvin cycle and how they’re connected. The light-dependent reactions take place in the thylakoid membrane.
What are the steps of photosynthesis in order?
Terms in this set (7)
- Step 1-Light Dependent. CO2 and H2O enter the leaf.
- Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
- Step 3- Light Dependent. The electrons move down to enzymes.
- Step 4-Light Dependent.
- Step 5-Light independent.
- Step 6-Light independent.
- calvin cycle.
What is Stage 1 of photosynthesis called?
Stages of Photosynthesis Stage I is called the light reactions. This stage uses water and changes light energy from the sun into chemical energy stored in ATP and NADPH (another energy-carrying molecule). This stage also releases oxygen as a waste product.
What does the H stand for in photosynthesis?
A biological molecule that has the elements carbon (C), hydrogen (H), and oxygen (O) in a ratio of 1:2:1. Carbs provide energy to cells, can be used for energy storage, and provide structural support.
How are the complex reactions of photosynthesis summarized?
The complex reactions of photosynthesis can be summarized by the chemical equation shown in Figure 5. Figure 5. The process of photosynthesis can be represented by an equation, wherein carbon dioxide and water produce sugar and oxygen using energy from sunlight.
How does the process of photosynthesis change life on Earth?
The process of photosynthesis transformed life on earth. By harnessing energy from the sun, photosynthesis allowed living things to access enormous amounts of energy. Because of photosynthesis, living things gained access to sufficient energy, allowing them to evolve new structures and achieve the biodiversity that is evident today.
What are the sugar molecules produced in photosynthesis?
After the process is complete, it releases oxygen and produces glyceraldehyde-3-phosphate (GA3P), as well as simple carbohydrate molecules (high in energy) that can then be converted into glucose, sucrose, or any of dozens of other sugar molecules. These sugar molecules contain energy and the energized carbon that all living things need to survive.
How does light dependent and light independent reactions occur in photosynthesis?
Light-dependent and light-independent reactions are two successive reactions that occur during photosynthesis. In light-dependent reactions, the energy from sunlight is absorbed by chlorophyll and converted into chemical energy in the form of electron carrier molecules like ATP and NADPH.
