Which diagrams shows reaction pathway that absorbs energy?

Biology
1 answer:
postnew [5]3 years ago
8 0

Question:

<em>The diagram shows the potential energy changes for a reaction pathway.</em>

Part 1: Does the diagram illustrate an endothermic or an exothermic reaction? Give reasons in support of your answer.

Part 2: Describe how you can determine the total change in enthalpy and activation energy from the diagram and if each is positive or negative.

Answer:

Part 1: The diagram illustrates an endothermic  reaction as the products has a higher potential energy than the reactants do. There is a positive slope of the diagram and there is enough energy to meet the activation energy requirement.

Part 2: You can determine the total change in enthalpy and activation energy from the diagram by the potential energy of the reactants. If the reactants have a high potential energy, then the enthalpy is also high, and if the reactants have a low potential energy, then the enthalpy is low. You can determine if the diagram is positive or negative by knowing if its an endothermic or exothermic reaction. An endothermic reaction is positive because the products are higher than the reactants and a exothermic reaction is negative because the reactants are higher than the products.

ziro4ka [17]

Answer:

The different possible genotypes are AA, AO, BB, BO, AB, and OO. These are derived according to the A, B and O blood group model.

The table is given below:

Blood Type Genotype

Blood Type A Genotypes AA or AO

Blood Type B Genotypes BB or BO

Blood Type AB Genotype AB

Blood Type O Genotype OO

The alleles A and B exhibit a greater dominance than O. This is the reason why the Parent of Blood type A will form the Genotype AO.

Which example demonstrates metabolism? (brainly wont let me see other answers ;( )
Artist 52 [7]

The group of chemical processes in organisms that maintain life is known as metabolism. The three primary functions of metabolism are: converting the energy in food into energy that can be used to power cellular functions.

It is convenient to divide metabolism into two groups: Molecules are broken down during catabolism to provide energy. All of the substances that the cells require are synthesised during anabolism. Metabolic processes include the chemical reactions that keep you alive. One example of metabolism is the rate at which you burn fat and consume calories. the constant anabolic and catabolic chemical and physical processes that occur in living things and their cells. Specific areas of the cell host metabolic events. The cytoplasm is where amino acid degradation and some phases of glycolysis, fatty acid synthesis, and glycogen synthesis take place. Within mitochondria, certain metabolic pathways are located at particular points.

DNA Damage: Causes and Effects
The most significant consequence of oxidative stress in the body is thought to be damage to DNA. DNA may be modified in a variety of ways, which can ultimately lead to mutations and genomic instability. This could result in the development of a variety of cancers including colon, breast, and prostate. Here we discuss the various types of damage to DNA, including oxidative damage, hydrolytic damage, DNA strand breaks, and others.

How does the respiratory system affect the cardiovascular system
Anit [1.1K]

Blood is the fuel that keeps you going! Oxygenated blood is brought to organs and tissues via the arteries, while veins bring deoxygenated blood back to the heart to be replenished. The point is, without the respiratory system your blood would be useless.

The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
