Which of the following statements about enzymes is false?
А Enzymes are made up of amino acids.
B Enzymes make otherwise slow reactions proceed more quickly.
C Enzymes provide energy for endergonic reactions.
D. Enzymes are usually specific for the chemical reactions they catalyze.​

Answers

B is false, enzymes speed up the reaction by lowering the activation energy needed for the reaction to start.

Answers B

The false statement about enzyme is - option C. Enzymes provide energy for endergonic reactions.

Enzymes are protein acts as biological catalysts. Enzymes increase the rate of reactions by lowering the activation energy.

Enzymes are made from amino acids. The chain of amino acids then folds into a unique shape.These are specific for the chemical reactionsEnzymes are biological catalysts that increase the rate of chemical reactions inside cells by lowering the activation energy therefore can not provide energy.Enzymes make slow reactions proceed more quickly.

Thus, the false statement is - option C.

What is Cell division?

Cell division is the process by which a parent cell divides into two new daughter cells. Cell division usually occurs as a part of a larger cell cycle in which the living cell grows and replicates its chromosome before undergoing division.

Cell division occurs in living cells through mitosis and meiosis. The cell division occurs through karyokinesis and cytokinesis. Cell division is a part of the cell cycle. Cell cycle is divided into different phases such as G1 phase, S phase, G2 phase, and M phase.

Each phase may be used more than once.Question Selected MatchAll 4 cardiac valves are closed and all 4 chambers are relaxed during this phase.The maximum amount of blood is in the ventricles at the end of this phase.The pressure in the ventricles is higher than in the atria, but lower than in the arteries, during this phase.The semilunar valves are open and the AV valves are closed during this phase.The atria contract at the end of this phase.The pressure in the ventricles is higher than the pressure in both the atria and the arteries during this phase.Systole begins with this phase.All Answer ChoicesA.ventricular ejectionB.ventricular fillingC.isovolumetric relaxationD.isovolumetric contraction

Answers

Answer:

1. Isovolumetric relaxation.

2. Ventricular filling.

3. Isovolumetric contraction.

4. Ventricular ejection.

5. Ventricular filling.

6. Ventricular ejection.

7. Isovolumetric contraction.

Explanation:

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

Diastole: in this stage, the ventricles is relaxed and would be filled with blood. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

The following terms describe the physical or mecahnical events with the correct phases of the cardiac cycle in mammals (human beings).

1. Isovolumetric relaxation: All 4 cardiac valves are closed and all 4 chambers are relaxed during this phase.

2. Ventricular filling: The maximum amount of blood is in the ventricles at the end of this phase.

3. Isovolumetric contraction: The pressure in the ventricles is higher than in the atria, but lower than in the arteries, during this phase.

4. Ventricular ejection: The semilunar valves are open and the AV valves are closed during this phase.

5. Ventricular filling: The atria contract at the end of this phase.

6. Ventricular ejection: The pressure in the ventricles is higher than the pressure in both the atria and the arteries during this phase.

7. Isovolumetric contraction: Systole begins with this phase.

The zika virus was first identified in Uganda in 1947. The virus is transmitted from person to person by a bite from a mosquito. It is commonly carried by the Aedes mosquito which is prevalent throughout Central Africa. The virus has more recently spread to the Americas (South, Central, and now North) and is expected to spread to Europe. There is a concern that the virus may reach epidemic proportions. Zika virus is related to yellow and dengue fever. Common symptoms are low grade fever and a distinctive skin rash and other symptoms include vomiting, headache, and muscle and/or joint pain. Pregnant women should avoid traveling to areas known to have zika virus present because the virus is known to cause microcephaly and developmental difficulties related to the central nervous system. Based on the paragraph above, class discussions, and other VALID (be careful with your selection of e-materials! CDC – Center for Disease Control is a good place to start) sources of information please answer the following questions.
1. State a reason why the virus has spread to the Americas and likely to spread to Europe.
2. Define the term microcephaly.
3. What bones of the fetal skull would be affected by zika? Specifically, what area of the CNS is not fully developed in microcephalic individuals.

Answers

Answer:

1. It is a highly contagious disease transmitted from person to person and thereby it is expected that infected persons carried the virus to America  

2. Microcephaly is a serious birth defect where a baby’s head is much smaller than expected.

3. Occipital bone. CNS malformations: ventriculomegaly, parenchymal and periventricular calcifications and cortical migration anomalies

Explanation:

The Zika virus (Flaviviridae) causes a contagious disease and it is transmitted by Aedes mosquitoes, which are also the main vectors of the dengue virus. Microcephaly is a condition where the baby’s brain has not developed properly during pregnancy, and it has been shown that this birth defect is associated with the Zika virus. During 2015 in Brazil, the incidence of infants with microcephaly born from mothers that contracted this disease during pregnancy was higher, thereby suggesting an association between both conditions. Baby health problems associated with Zika infection include microcephaly (skull partially collapsed), joints with limited motion, etc.

Answers

Answer:

The gene, or sequence of DNA, ultimately determines the unique sequence of amino acids in each peptide chain. A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and therefore function.
