No, yeast does not produce carbon dioxide (CO2) during aerobic respiration. In aerobic respiration, yeast uses oxygen to completely break down glucose into carbon dioxide and water, resulting in CO2 as a byproduct. However, the process is more efficient than anaerobic respiration, where yeast ferments sugar and produces both ethanol and CO2. So, while CO2 is produced in aerobic conditions, it is not the primary energy-generating pathway for yeast.
What else can I help you with?
Does a higher percent of transmittance mean there is more aerobic respiration?
A higher percent of transmittance in a solution typically indicates that more light is passing through, suggesting lower absorbance by the substances present. In the context of aerobic respiration, if transmittance is measured for a product like carbon dioxide or a byproduct of respiration, a higher percent could imply more aerobic respiration is occurring. However, transmittance alone doesn't directly measure respiration; it must be considered alongside other factors like the specific substances being analyzed.
Which product of aerobic cellular respiration could not form in an anaerobic environment?
In an anaerobic environment, aerobic cellular respiration cannot fully occur, leading to the absence of oxygen as the final electron acceptor in the electron transport chain. As a result, one key product of aerobic respiration, ATP, is produced in much lower amounts, and the byproducts of the process, such as water, cannot form. Instead, cells may rely on anaerobic processes like fermentation, which generate different byproducts and significantly less ATP.
Why do most complex organisms undergo aerobic respiration rather than anaerobic respiration?
During anaerobic respiration, such as fermentation, pyruvic acid and NADH form the products of alchohol and carbon dioxide and NAD+. In aerobic respiration there are many more steps in the Krebs cycle to make the products of carbon dioxide, NADH, ATP, and FADH2 from pyruvic acid.Therefore aerobic respiration is much more complex than aerobic respiration.
How would you demonstrate that oxygen is used up during aerobic respiration?
To demonstrate that oxygen is used up during aerobic respiration, you can set up a simple experiment using respirometers containing organisms like yeast or small insects. By placing the organism in a sealed chamber with a gas sensor or using a setup with a manometer, you can measure the decrease in oxygen levels over time. Additionally, you could use a dye that changes color in the presence of oxygen to visually indicate the consumption of oxygen during the respiration process. The observed decrease in oxygen levels confirms its utilization in aerobic respiration.
How could evolution of aerobic respiration have permitted evolution of more complex organisms?
An oxygen-based metabolism provides more energy than an anaerobic metabolism, allowing for a larger volume-to-surface ratio of organisms. So organisms could grow larger, allowing their tissues to specialize in various ways, which means increasing complexity.
What are the possible events that could happen after glycolysis?
It either undergoes Anaerobic or Aerobic Cellular Respiration.
This is the process that releases energy by breaking down food molecules in the presence of oxygen.?
The glycolysis and the Krebs cycle uses the oxygen to break down the food molecules in order to release energy.
Which process in living things evolved as oxygen levels increased in earths atmosphere?
Aerobic respiration evolved as oxygen levels increased in Earth's atmosphere. This process allows living organisms to efficiently extract energy from food by using oxygen to break down glucose molecules and produce ATP. As oxygen became more abundant, organisms that could perform aerobic respiration gained a significant evolutionary advantage.

However, transmittance alone doesn't directly measure respiration; it must be considered alongside other factors like the specific substances being analyzed.
Why does your body use anaerobic respiration?
Your body uses anaerobic respiration when there is not enough oxygen available to produce energy through aerobic respiration. Anaerobic respiration produces energy quickly but less efficiently, resulting in the accumulation of lactic acid as a byproduct which can cause muscle fatigue and soreness.

Can electricity be produced from respiratory pressure difference?
Respiration could be measured by using a suitable transducer. A moving coil, with permanent magnet, could produce an electrial signal measuring respiration. An alternative would be to use a piezoelectric crystal. This creates a small voltage when mechanically bent or shocked. Suitable attachment, would produce a signal with respiration.
How much more atp does aerobic respiration produce than glycolysis?
Aerobic respiration produces about 18 times more ATP than glycolysis. Glycolysis generates 2 ATP molecules per glucose molecule, while aerobic respiration can yield up to 36-38 ATP molecules per glucose molecule.
What would happen if organisms could not obtain oxygen?
If organisms could not obtain oxygen, they would not be able to carry out aerobic respiration, which is essential for producing energy. This would result in cell death and ultimately lead to the death of the organism. Anaerobic respiration could provide some energy, but it is less efficient and may not sustain life in the long term.
How did the physical evidence collected in this investigation support the hypothesis that yeast carry on respiration?
The physical evidence collected in the investigation, such as the measurement of carbon dioxide production or the observation of bubbles during fermentation, supported the hypothesis that yeast carry on respiration. These findings indicated that yeast metabolize sugars and produce gases as byproducts, demonstrating their aerobic or anaerobic respiration processes. Additionally, changes in temperature or pH levels could further confirm the metabolic activity of yeast, reinforcing the idea that they actively respire. Overall, the evidence aligned with the expected outcomes of yeast respiration.
