During cellular respiration, glucose molecules undergo a series of reactions. This process results in the formation of up to 38 molecules of high-energy ATP per each molecule of glucose. Which is the source of the energy stored in these ATP molecules?
chemical energy originally stored in the glucose molecule
potential energy from the difference in the concentration gradients of the cell
kinetic energy generated by the chemical reactions
electric current created during the destruction of electrons in the glucose
Answer:
1.Sugar bonds
2.Transport proteins
3. Digestion
4. Oxidation
explanation
Chemical energy is stored in the bonds of sugar.
The concentration gradient of a substance across the membrane represents potential energy bcz it drives diffusion.Transport proteins aids the diffusion.
Digestion converts chemical energy into kinetic energy used by cells.
When the electrons are destroyed in the glucose,Energy contained in the bonds is released in small bursts,some of it is captured in the form of ATP .'The electrons are transferred to smaller molecules known as electron carriers.The electron carriers take the electrons to a group of proteins in the inner membrane of the mitochondrion,called the electron transport chain.As electrons move through the electron transport chain they go from a higher to lower energy level and are finally passed to Oxygen to form water.The energy released is captured as a proton gradient which powers the production of ATP.
Not 100% sure whether it's the correct answer but the concept is true 100% btw I stand to be corrected
Answer:
A. Chemical energy originally stored in the glucose molecule.

Which statement BEST describes the measurements he would find in the jar, in the experiment group, B, compared with the concentrations of oxygen and carbon dioxide in the classroom air?
The provided question is incomplete as the important part and group of choices was missing, however, the correct question is given below:
In an experiment, Tony placed a potted plant under a bell jar, completely sealing the jar to the tabletop. After placing a box over the bell jar for 24 hours, he measured the concentrations of oxygen and carbon dioxide in the gas in the jar. Which statement best describes the measurements he would find in the jar, compared with the concentrations of oxygen and carbon dioxide in the classroom air?
Concentrations of both carbon dioxide and oxygen decreased.
Concentrations of both carbon dioxide and oxygen increased.
Carbon dioxide concentration increased; oxygen concentration decreased.
Oxygen concentration increased; carbon dioxide concentration decreased.
Answer:
The correct answer would be - Carbon dioxide concentration increased; oxygen concentration decreased.
Explanation:
There are two major processes respiration and photosynthesis that help in the production and utilizing the carbon dioxide and oxygen in plants. In order for your plant to grow photosynthesis is the process that converts carbon dioxide into glucose and oxygen. Photosynthesis only occurs in the daylight process so the use of carbon dioxide and producing oxygen is limited.
On the other hand, respiration is a continuous process that uses oxygen and glucose to produce carbon dioxide therefore the correct answer is Carbon dioxide concentration increased; oxygen concentration decreased

Question #21
In the field of medicine, researchers have recently designed a technique that allows them to use adult
stem cells to test the potency and safety of newly designed drugs for humans. What is the most
likely advantage of this new technology compared with other forms of drug trials?
A
It helps ensure that the shelf life of newly designed drugs is as long as possible.
B
It helps ensure that the newly designed drugs can cure all patients they are used to treat.
C
It helps reduce the demand to test newly designed drugs on animals.
D
It helps reduce the time it takes to bring newly designed drugs to the market.
Answer:
The answer is B
Explanation:
The technique that allows them to use stem cells to test the potency and safety of newly designed drugs for humans, helps reduce the time needed to bring newly designed drugs to market.
The stem cells to test newly designed drugs for humansUse important stem cells to define the toxicity of new drugs presented results in preliminary tests. The rational use and search for alternative methods to the use of animals in scientific research is currently a worldwide concern. However, despite the stages of the scientific community, it is still not possible to open animal experimentation in the so-called pre-clinical development of new drugs and other products for human health.
With this information, we can conclude that the technique that allows them to use stem cells to test the potency and safety of newly designed drugs for humans, helps reduce the time needed to bring newly designed drugs to market.

What two things below most affect the amount of dissolved oxygen in water?
Answer:
Dissolved oxygen levels will fluctuate with temperature
Explanation:
While water equilibrates toward 100% air saturation, dissolved oxygen levels will also fluctuate with temperature, salinity and pressure changes ³. As such, dissolved oxygen levels can range from less than 1 mg/L to more than 20 mg/L depending on how all of these factors interact.

11. Why is the age of the earth important to Darwin's theory of evolution?
Answer:
Darwin's theory of evolution is when species are taking time to evolve from the original organism so in order for this to happen there has to be an original species so he also said that we came from apes if the world was 200 years old that still wouldn't be enough time for us to evolve how he said so in order for his theories to be even remotely correct it took time for this to happen so the age of the earth in a way helps support his theory

Imagine customers moving into and out of a coffee shop. Which situation
resembles how a reaction in dynamic equilibrium acts?
A. There are the same number of people inside the coffee shop as
outside it.
B. People enter the coffee shop at the same rate as others leave.
C. No people are moving either into or out of the coffee shop.
D. Some people sit down and drink their coffee slowly, while others
drink theirs quickly while standing up.
No
Answer:
B. People enter the coffee shop at the same rate as others leave.
Explanation:
did the test !!
The answer is B. People enter the coffee shop at the same rate as others leave.
In a reaction in dynamic equilibrium, the forward and reverse reactions occur at the same rate, meaning that the concentrations of reactants and products remain constant over time.
Similarly, in the coffee shop scenario, if people are entering and leaving at the same rate, the number of customers inside the shop will remain constant, just like the concentrations of reactants and products in equilibrium.
Option A, C, D are not a good analogy for dynamic equilibrium.

Which of these activities would be least likely to help scientists explain the origin of life on Earth? determining how pollution is affecting life in the ocean
determining how the atmosphere became rich in oxygen
determining how cells could develop from nonliving matter
determining how organelles developed from symbiotic organisms
Answer:
B
Explanation:
Determining how the population affects life in the ocean is the least likely to help scientists explain the origin of life on Earth. Therefore, option A is correct.
What is the origin of life?The origin of life means the emergence of organisms on earth. Many scientists tried to explain how life originated on the earth and gave various theories, like panspermia, common descent, gradualism, natural selection, etc.
The first organism that originated on the earth was microbes in water. When the earth formed, it was reduced in nature. Gradually oxygen formed on the earth which was very helpful in the origin of life. Some theories explained how cells could develop from nonliving matter.
determining how the population is affecting life in the ocean is not related to the origin of life. Hence, option A is correct.
