Adenosine triphosphate (ATP) is a cell's energy currency. All of the following statements about ATP are true, except ATP is used to lower activation energy in enzymatic reactions.
A) ATP is used to lower the activation energy in enzymatic reactions.How does ATP affect enzyme activity?Enzymes allow chemical reactions to proceed with activation energy provided by the catabolism of ATP. When cells convert glucose and oxygen into carbon dioxide and water, they use 2 molecules of ATP as activation energy and gain 36 to 38 molecules of ATP in return. Without enzymes, this would not be possible.

Answers
From observation of the graph, the likely height of the tree in meters at day 10 is given at 2 meters. Option A.
What is the explanation for the above?When working with graphs, data is first plotted then a relationship is deduced by drawing a line of best fit which connects the data points together.
It is to be noted that the data points on the graph suggest and indicate that the most likely height of the tree in meters at 10 days is 2.
It is to be noted that the graph of a function "f" is the set of ordered pairings where f(x)=y in mathematics.
When x and f(x) are both real values, these pairings represent Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane.

Answers
The two required components to initiate transcription on the gene are:
Transcription factors that bind to the promoter sequences Mediator proteins - binds to enhancer and promoter regions in the gene.What is transcription of a gene?Transcription of a gene is the process by which the information present in the gene is used to produce the messenger RNA molecule by RNA polymerase.
A gene is a sequence in the DNA molecule which codes for a particular gene product.
The process of transcription is important or the first step which is required in the production of the gene product of a gene.
In order for transcription of a gene to be initiated, certain components are required. These components include:
Transcription factors - these are proteins that bind to the promoter sequences as well as other regulatory sequences in the gene.

Which of the following is likely to describe a metabolic reaction where the net delta G value is positive?
spontaneous or non-spontaneous
catabolic or anabolic
positive delta E or negative delta E
Answers
The non spontaneous, anabolic and positive delta E are some of the reaction where net delta G is positive.
What are metabolic reactions?The Gibbs free energy difference between a reaction's products and reactants is known as delta G.
The response is spontaneous if Delta G is negative, non-spontaneous if it is positive, equilibrium if it is zero, and non-spontaneous if it is negative. If dH is positive and dS is negative according to the equation dG = dH - dS*T, then delta G is positive.
Delta G is negative if dH is negative and dS is positive. It depends on the temperature at which the reaction is taking place whether dH and dS are both positive or both negative.
Therefore, The non spontaneous, anabolic and positive delta E are some of the reaction where net delta G is positive.

2H₂O2 -> 2H₂O + O₂
2H₂O + O₂->> 2H₂O2
Answers
The reaction 2H₂O2 -> 2H₂O + O₂ shows Catalase reaction. The correct option is 3.
What is Catalase reaction?The catalase reaction encompasses the breakdown of hydrogen peroxide (H₂O₂) into water (H₂O) and oxygen (O₂).
The enzyme catalase facilitates this reaction. The reaction is represented by the equation: 2H₂O₂ -> 2H₂O + O₂.
This means that when two molecules of hydrogen peroxide react, two molecules of water and one molecule of oxygen are formed.
The presence of the enzyme catalase, which speeds up the reaction and allows it to occur under normal physiological conditions, makes this reaction possible.
The Catalase reaction is an important process that aids in the breakdown of harmful hydrogen peroxide into harmless water and oxygen in living organisms.

The properties of the elements in the periodic table show a regular variation across the vertical columns and the horizontal rows. This variation in property is known as periodicity.
The vertical columns are called groups or families whereas the horizontal rows are called periods.
