How does photosynthesis occur? (Provide the chemical equation)
6CO2 + 6H2O ==light energy and chlorophyll==> C6H12O6 + 6O2
What is photosynthesis?
Photosynthesis is the process where plants convert light energy into energy (glucose). P
How is carbon dioxide/oxygen absorbed/released in the process of photosynthesis?
Carbon dioxide and oxygen flow through the semi-permeable membrane of the stomata in a leaf through diffusion.
What carries water from the roots of a plant and carries the glucose from the leaves to the roots?
Xylem in a plant’s trunk or stem are what carries water to the leaves from the roots.
Phloem in a plant’s trunk or stem are what carries glucose to the roots from the leaves.
What is the purpose of chlorophyll in photosynthesis?
In photosynthesis, chlorophyll is used to absorb the light energy from its source so it can facilitate the chemical reaction.
What is cellular respiration?
Respiration is a combustion reaction. Respiration is a process which breaks down sugar molecules and in order to convert them into energy. The kind of energy produced is known as ATP.
What are the two types of cellular respiration?
The two kinds of cellular respiration are:
- aerobic respiration (with the presence of oxygen)
- anaerobic respiration (without the presence of oxygen)
How does cellular respiration occur? (Provide the chemical equation)
6O2 + C6H12O6 =====> 6H2O + 6CO2 + ATP energy
What are the two steps of cellular respiration?
- Glycolysis - breaks down glucose into two pyruvate and gains 2 ATP
- Breaking down the pyruvate
Why is aerobic respiration more effective than anaerobic respiration?
Aerobic respiration fully breaks down the pyruvate producing 36 ATP while anaerobic respiration only partially breaks down the pyruvate producing only 2 ATP.
What are the products anaerobic respiration in yeast cells?
Alcohol, energy and carbon dioxide.
What is the product of anaerobic respiration in human muscle cells?
Lactic acid.
Where does cellular respiration occur?
In eukaryotes, respiration happens mainly in the mitochondria however glycolysis occurs in the cytoplasm.
In prokaryotes, respiration occurs in the cytoplasm or inner surfaces of the cell.
List three uses of energy stored in ATP.
Movement
Growth
Maintaining temperature
State two everyday or industrial uses for the anaerobic respiration reaction in yeast cells.
Brewing industry (beer) Baking industry (bread)
