Which equation best describes the process of cellular respiration in humans?
The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O.
What is the first step of cellular respiration?
In glycolysis, the beginning process of all types of cellular respiration, two molecules of ATP are used to attach 2 phosphate groups to a glucose molecule, which is broken down into 2 separate 3-carbon PGAL molecules. PGAL releases electrons and hydrogen ions to the electron carrier molecule NADP+.
What is the chemical equation of respiration?
The word equation for respiration is: Glucose + Oxygen = Carbon Dioxide and Water The chemical equation is C6H1206 + O2 = CO2 + H20 Respiration is used by all living humans and animals, to make energy for movement, heat and to keep vital organs running, without it we’d be dead.
What are the three steps of cellular respiration?
Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. Glycolysis is an anaerobic process. The other two stages are aerobic processes. The products of cellular respiration are needed for photosynthesis, and vice versa.
What is the correct order of the stages of cellular respiration?
Ch. 9 Honors Biology Cellular Respiration
| Question | Answer |
|---|---|

| What is the correct equation for cellular respiration? | C6H12O6 + 6 O2 –> 6 CO2 + 6 H2O |
| What are the products of cellular respiration? | CO2, H2O, ATP |
What are the two steps of aerobic respiration?
Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. This results in a net gain of two ATP molecules. Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.
What is the site of reaction of aerobic respiration?
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell….Aerobic vs anaerobic respiration.
| Aerobic | Anaerobic | |
|---|---|---|
| Location | Cytoplasm (glycolysis) and mitochondria | Cytoplasm |
What are examples of aerobic respiration?
When the breakdown of glucose food occurs with the use of oxygen ,it is called aerobic respiration. Glucose___oxygen _____co2 +water + energy. For example -Human ,dogs ,cats and all the animals and birds ,insects ,grasshopper etc many more and most of the plants carry out aerobic respiration by using oxygen of air.
What is the similarities and differences between aerobic and anaerobic respiration?
The similarities between aerobic and anaerobic respiration, is that they both use glucose as the starting molecule. This is called the substrate. In addition, both aerobic and anaerobic respiration produce ATP, however, aerobic respiration produces a lot more ATP compared to anaerobic respiration.
What process requires oxygen function?
Aerobic Metabolism Any metabolic process that requires oxygen to occur is referred to as aerobic. Humans, most other multicellular organisms, and some microorganisms require oxygen for the efficient capture of the chemical energy from food and its transformation into the cellular energy form known as ATP.
What are the advantages of aerobic respiration?
A major advantage of aerobic respiration is the amount of energy it releases. Without oxygen, organisms can split glucose into just two molecules of pyruvate. This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide.
Why didn’t Stanley make any wine?
Why didn’t Stanley make wine? Stanley didn’t make wine as he exposed his yeast to air in an open container and it didn’t ferment. Bacteria could have also contaminated it, and it wasn’t fresh yeast.
Why will contaminating bacteria make wine sour while pure yeast will not?
Answer: The bacteria can make the wine sour but the yeast will not. Yeast can grow in the presence of air or in the absence of air. Certain contamination with bacteria can convert pyruvate to acetic acid instead of alcohol which gives sour taste to the alcohol.
Why does Stanley redesign his original experiment?
What does Stanley need to do to redesign his original experiment? Stanley needs to insure the absence of oxygen for fermentation to take place, therefore he can use a lid for the glass to create vacuum, or any other alternative dishes to the glass with the lid.
How are yeast and bacteria different in fermentation?
Yeast have a prominent role in the production of beverages, due to the ability to accumulate high levels of ethanol and to produce highly desirable aroma compounds, but lactic acid bacteria are particularly important in fermentation because they produce desirable acids, flavor compounds, and peptides that inhibit the …
What is the relationship between yeast and bacteria?
Bacteria and Yeast are not related in any genetic sense. Yeast, by and large, eat sugar and produce alcohol and various esters and phenols (and CO2). To most brewers (and vintners), though, the only yeast of any consequence is Saccharomyces, and any other microbe is to be avoided at all costs.
Does fermentation kill bacteria?
Some fermented foods are pasteurized after fermentation, which kills all live bacteria and allows for a longer storage time. However, these foods don’t provide the health benefits of live bacteria cultures.
Which bacteria helps in fermentation?
Fermentation bacteria are anaerobic, but use organic molecules as their final electron acceptor to produce fermentation end-products. Streptococcus, Lactobacillus, and Bacillus, for example, produce lactic acid, while Escherichia and Salmonella produce ethanol, lactic acid, succinic acid, acetic acid, CO2, and H2.
What is the main goal of fermentation?
The main function of fermentation is to convert NADH, a chemical compound found in all living cells, back into the coenzyme NAD+ so that it can be used again. This process, known as glycolysis, breaks down glucose from enzymes, releasing energy.
Which bacteria is present in idli batter?
The fermentation of idli demonstrates a leavening action caused by the activity of the heterofermentative lactic acid bacterium, L. mesenteroides. As far as is known, this is the first record of a leavening action produced exclusively by the activity of a lactic acid bacterium.
What is fermentation and its types?
An important way of making ATP without oxygen is called fermentation. It involves glycolysis, but not the other two stages of aerobic respiration. Many bacteria and yeasts carry out fermentation. There are two types of fermentation: lactic acid fermentation and alcoholic fermentation.
