During glycolysis, the molecule glucose is broken down into pyruvate. What type of reaction is this?

Answers

Explanation:

Glycolysis is a set of anaerobic reactions, ones that does not need oxygen to be performed. It takes glucose and breaks it down into pyruvate. This has the result of creating two ATP, which can release energy.

Overall, this process creates four ATP, but it uses two ATP early in the reaction. This means that there is a net gain of two ATP.

The overall equation for this pathway is:

1 glucose + 2 ATP ⟶ 2 pyruvate + 2 NADH + 4 ATP + 2 H2O

Glycolysis is a set of anaerobic reactions, ones that does not need oxygen to be performed. It takes glucose and breaks it down into pyruvate. This has the result of creating two ATP, which can release energy.

Overall, this process creates four ATP, but it uses two ATP early in the reaction. This means that there is a net gain of two ATP.

What does glycolysis process?

Glycolysis is the method of breaking down glucose. Glycolysis can take place with or without oxygen. Glycolysis produces two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water.

Glycolysis occurs in the cytoplasm.

Thus, Glycolysis is the method of breaking down glucose. Glycolysis occurs in the cytoplasm.

If a DNA strand contains 12% thymine, it also contains ____

a. 12% A, 38% G, 38% C
b. 12% A, 12% G, 38% C
c. 12% A, 12% G, 12% C
d. 38% A, 12% G, 38% C

Answers

Answer:

If G = 14, then C = 14 and G + C is 28. Thus A + T. The percent of adenine in a double-stranded DNA is 38. Therefore G + C = 100 - 76 = 24, and C = 24/2 = 12 percent.  

Explanation:

A=T
so A is 12% too
100-(12+12)
=100-24
=76
then divide by 2 to get each C and G
76/2=38
so C and G are each 38%

the answer is option A

(Brainly needs to realize if they let us talk about college biology, that we are going to use words that have h.o.m.o. and that they are genuinely correct scientific terms.

Answers

P is parent gene, and then the offspring goes to the F1 and then F2, the dominant gene is what gene wins over a recessive. So the answer is c

The preferred generation of hybrid offspring is called the P generation and can often be used to determine the dominant gene.

What is P generation and dominant?

Dominant directs to the relationship between two versions of a gene. Then, Individuals receive two versions of each gene, which are called alleles, from each parent. When the alleles of a gene are different, So, one allele will be expressed This is a dominant gene.

When The P generation is the start of Mendel's work on inheritance, or receiving genetic qualities by transmission from parent to offspring. So, Basically that it refers to traits or genes that are passed from a parental generation to its offspring

When P is the parent gene, and also then the offspring goes to the F1 and also then F2, the dominant gene is what gene wins over a recessive. So the correct option is 'C'.

Macronutrients can be stored by the body for later use when it enters into the fasted state.

a. True
b. False

Answers

Answer:

a. True

Explanation:

The statement being made is true. The Fasted State is where our bodies draw  from glycogen and fat reserves in order to create energy. This happens only when we do not eat that we enter into this state. The body first needs to draw all the energy it can from the glycogen stores and then once that is depleted it then begins to draw from fat stores for energy. Using all the stored macronutrients and turning them into energy to sustain the body.
