Glycolysis is the first step of cellular respiration, in which glucose is used to generate ATP to power the cell. The major chem

ical reaction that takes place in glycolysis (ignoring some other reactants and products) is the conversion of glucose (C6H12O6) to pyruvate (C3H4O3) and hydrogen ions (H+). Using this information, what is the correct equation for the glycolysis chemical reaction?
a. C6H12O6 -> C3H4O3+H+
b. C6H12O6 -> 2 C3H4O3+2 H+
c. C6H12O6 -> 2 C3H4O3+H+
d. 2 C6H12O6 -> C3H4O3+2 H+

Answer:

The correct answer is b. C6H12O6 -> 2 C3H4O3+2 H+

Explanation:

Glycolysis occurs in both the condition aerobic and anaerobic so it does not require oxygen. In glycolysis, one glucose molecule is converted into two pyruvate( 2 C3H4O3) and two 2 ATP, 2NADH, and 2 H₂O are produced.

Initially, 2NAD⁺ is produced during glycolysis which is reduced to produce 2NADH and 2 H⁺. Therefore the correct equation is  C6H12O6 -> 2 C3H4O3+2 H+.

Then this pyruvate is used in the Kreb cycle which is required for the complete breakdown of glucose into carbon dioxide and water and this process occurs in aerobic conditions. Complete oxidation is important to produce more energy from partially oxidized glucose.

The essential difference between an experiment and an observational study is that a. observational studies always involve large
Nataly_w [17]

Answer:

An experiment imposes treatment on the subjects, but an observational study does not

Explanation:

Observational studies are research studies in which an effect, process behaviour etc. are observed, without any change. For example, observation of the  possible effect of a treatment on subjects.

On the other hand, experimental studies are studies in which the treatment is included. Experimental studies are randomized, meaning that subjects that are in experiment are randomly put to a treated group or a control group.

What happens when the net energy is zero
drek231 [11]

Answer:   Zero Net Energy = Zero Net Emissions

Explanation:   With the addition of renewable energy generation, a ZNE building's annual energy costs become negligible, and since there is a net-zero balance of energy production and use, your building's carbon footprint with respect to energy consumption would also approach zero.

The lock-and-key analogy for enzymes applies to the specificity of enzymes _____. A) as they form their tertiary and quaternary
xeze [42]

The correct answer is: B) binding to their substrate

The catalytic mechanism of an enzyme starts when the substrate binds to its active site (specific region of an enzyme). There is a theory (lock and key) that explains the mechanism of this binding: the lock is the enzyme and the key is the substrate and only if they fit the enzyme will work. The binding of the substrate to the enzyme causes conformational changes of the enzyme, and as a result, products are formed. The products are then released from the surface of tat enzyme. The enzyme is regenerated for another reaction cycle.

Aloiza [94]

The question is incomplete as the group of choices are not provided. However, a group of choices is given below:

A. Do the young hemlocks have a disease?

B. Are deer eating most of the young hemlocks

C. Did a lack of rain the hemlocks to stop producing?

D. Why were there so many deer in the forest?

Answer:

The correct answer is - option B Are deer eating most of the young hemlocks .

Explanation:

By the observation made by the researcher about decreased young hemlocks and increased deer population in the last 5 year time period and findings of the deers that they like to eat young hemlocks, she can make observations and form the question.

On the following finding, she was able to make a question that the population of deer increased has led to the young Hemlock's population that the deer eat young Hemlocks.

Thus, the correct answer is - option B Are deer eating most of the young hemlocks .
