What is definition of photosynthesis?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
What Heterotroph means?
A heterotroph is an organism that eats other plants or animals for energy and nutrients. Autotrophs are known as producers because they are able to make their own food from raw materials and energy. Examples include plants, algae, and some types of bacteria.
Does photosynthesis produce ATP?
The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP.
What is the main product of anaerobic respiration?
Aerobic respiration vs anaerobic respiration
| Aerobic | Anaerobic | |
|---|---|---|
| Oxygen | Needed | Not needed |
| Glucose breakdown | Complete | Incomplete |
| End product(s) | Carbon dioxide and water | Animal cells: lactic acid. Plant cells and yeast: carbon dioxide and ethanol |
| Energy released | Relatively large amount | Relatively small amount |
What are 2 types of anaerobic respiration?
Anaerobic respiration occurs when the amount of oxygen available is too low to support the process of aerobic respiration. There are two main types of anaerobic respiration, alcoholic fermentation and lactic acid fermentation.
What are the 3 stages of anaerobic respiration?
Carbohydrates are broken down using all three stages of respiration (glycolysis, citric acid cycle and the electron transport chain).
What is end product of anaerobic respiration?
In anaerobic respiration, the end products are ethyl alcohol or lactic acid, and carbon dioxide.
What are the stages of anaerobic respiration?
Aerobic vs anaerobic respiration
| Aerobic | Anaerobic | |
|---|---|---|
| Location | Cytoplasm (glycolysis) and mitochondria | Cytoplasm |
| Stages | Glycolysis (anaerobic), Krebs cycle, oxidative phosphorylation | Glycolysis, fermentation |
| ATP produced | Large amount (36 ATP) | Small amount (2 ATP) |
What is anaerobic respiration formula?
Anaerobic respiration takes place in the cell cytoplasm and produces lactic acid. The chemical equation is C6H12O6 -> 2C3H6O3 (Glucose -> Lactic acid).
What are the products of anaerobic respiration in muscles?
The end products of anaerobic respiration are Lactic acid or ethanol and ATP molecules. Anaerobic respiration takes place in the absence of oxygen and is seen in lower animals.
Why do humans respire anaerobically?
You need to transfer energy from glucose to your muscles very quickly. However your body cannot get oxygen to its muscles quickly enough for aerobic respiration to occur. This is why anaerobic respiration happens instead.
How do muscles get oxygen?
Oxygen is supplied to the muscles via red blood cells. Red blood cells carry hemoglobin which oxygen bonds with as the hemoglobin rich blood cells pass through the blood vessels of the lungs. The now oxygen rich blood cells carry that oxygen to the cells that are demanding it, in this case skeletal muscle cells.
Which type of respiration is most efficient?
Aerobic respiration
What are the disadvantages of anaerobic respiration?
Disadvantages: Anaerobic respiration generates only two ATPs and produces lactic acid. Most lactic acid diffuses out of the cell and into the bloodstream and is subsequently absorbed by the liver. Some of the lactic acid remains in the muscle fibers, where it contributes to muscle fatigue.
What type of respiration requires oxygen?
aerobic respiration
Does fermentation need oxygen?
Fermentation does not require oxygen and is therefore anaerobic. Fermentation will replenish NAD+ from the NADH + H+ produced in glycolysis. One type of fermentation is alcohol fermentation. Facultative anaerobes are organisms that can undergo fermentation when deprived of oxygen.
Why is oxygen bad for fermentation?
Unless you use pure oxygen it is difficult to over-oxygenate your wort before fermentation. In early stages of yeast growth, the yeast will actually scrub all of the oxygen from the beer and use it to grow and expand. Oxygen, even in very small quantities is bad for finished beer.
Does boiling stop fermentation?
fermentation is not done by boiling. boiling would kill the yeast. yeast need a very specific temperature range to convert sugars (wort, grape juice, honey, whatever…) to alcohol. and boiling is far above the temperature in which yeast can survive.
What happens if oxygen is present during fermentation?
Pyruvic acid supplies energy to living cells through the citric acid cycle (also known as the Krebs cycle) when oxygen is present (aerobic respiration), and alternatively ferments to produce lactic acid when oxygen is lacking (fermentation).
Why does fermentation eventually cease?
Yeast cells produce ethanol (alcohol) in a process called fermentation. Why does fermentation eventually cease? When lactic acid builds up in the blood, a person is said to be in oxygen debt. This debt must eventually be paid.
Does yeast produce alcohol in the absence of oxygen?
Yeast (single-celled eukaryotic organisms) perform alcoholic fermentation in the absence of oxygen. The products of alcoholic fermentation are ethyl alcohol (drinking alcohol) and carbon dioxide gas.
What is the end product of lactic acid fermentation?
| Name of process | End products |
|---|---|
| Lactic acid fermentation | Lactate |
| Alcohol fermentation | Ethyl alcohol + CO2 |
Why does lactic acid fermentation occur in your body?
Your muscle cells can produce lactic acid to give you energy during difficult physical activities. This usually happens when there is not enough oxygen in the body, so lactic acid fermentation provides a way to get ATP without it.
What are 3 products of lactic acid fermentation?
What Are the Products of Lactic Acid Fermentation?
- Lactic Acid. One product of lactic acid fermentation is lactic acid itself.
- NAD+ The process of fermentation doesn’t actually yield energy.
- Pyruvate.
What is the difference between lactic acid and alcoholic fermentation?
Both types of fermentation occur in the cytosol. Lactic acid fermentation produces lactic acid molecules from pyruvate while alcoholic fermentation produces ethanol and carbon dioxide from pyruvate. The main difference between lactic acid and alcohol fermentation is the products of each fermentation.
