What happens to the enzyme activity of A after 30 degrees

1 answer:

3 0

The temperature of Enzyme activity of A is affected because the rate of an enzyme catalyzed reaction increases when temperature is raised.

Explanation:

The temperature can affect the enzyme in two different ways they are direct influence on the reaction rate constant and the thermal denaturation of the enzyme at elevated temperatures.

In an optimum condition there is a higher rate of reaction which states there is a lower Km and higher Vmax value. In lower temperature the Km value increases resulting lower affinity of substrates with the enzymes. The lower activity is due to the lower affinity of the substrates with the enzyme.

If the temperature is rised to ten degree then the activity of enzymes are increased to 50 to 100 %.

Which body system makes red blood cells?

forsale [732]

Answer:

In the human adult, the bone marrow produces all of the red blood cells, 60–70 percent of the white cells (i.e., the granulocytes), and all of the platelets. The lymphatic tissues, particularly the thymus, the spleen, and the lymph nodes, produce the lymphocytes (comprising 20–30 percent of the white cells).

Cells from advanced malignant tumors often have very abnormal chromosomes as well as an abnormal number of chromosomes. What mig

patriot [66]

Answer:

Option- D: Is the best choice to choose from the given options.

Now, let us explain the term Cell cycle in a more comprehensive way.

As the cell cycle is controlled at three checkpoints.

The integrity of the DNA is assessed at the G₁ checkpoint.

Proper chromosome duplication is assessed at the G₂ checkpoint.
Attachment of each kinetochore to a spindle fiber is assessed at the M checkpoint.

Explanation:

The cell cycle is controlled by three internal checkpoints that evaluate the condition of the genetic information.

The G₁ Checkpoint:This stage determines whether all conditions are favorable for cell division to proceed. The cell can halt the cycle and attempt to remedy the problematic condition, or the cell can advance into G₀ (inactive) phase and await further signals when conditions improve.
The G₂ Checkpoint: The most important role of the G₂ checkpoint is to ensure that all of the chromosomes have been accurately replicated without mistakes or damage.
The M Checkpoint:It occurs near the end of the meta-phase stage of mitosis. it determines whether all the sister chromatids are correctly attached to the spindle micro-tubules

Intercostal nerves Group of answer choices are also known as cervical nerves. do not enter into a plexus and directly connect to

Natali [406]

Answer:

The correct answer is: do not enter into a plexus and directly connect to the structures they supply.

Explanation:

The anterior rami of the thoracic spinal nerves from T1 to T11 give birth to the intercostal nerves, which are part of the somatic nervous system.

The intercostal nerves supply the thoracic pleura and abdominal peritoneum, and they vary from the anterior rami of the other spinal nerves in that they each take their own path without forming a plexus, directly connecting to the structures they supply.

The intercostal nerves are derived from the somatic nervous system, unlike the autonomic nervous system nerves that innervate the visceral pleura of the thoracic cavity. They can govern muscle contractions and give sensory information about the skin and parietal pleura as a result of this. This explains why damage to the thoracic cavity's interior wall can be felt as a severe discomfort in the damaged area. Damage to the visceral pleura causes a pain that is not localized.

The relationship between humans and their digestive bacteria can be described as... A) Commensalism B) Competition C) Mutualism

Flura [38]

Answer: The correct answer is -

C) Mutualism.

Explanation:

Mutualism is a type long term biological relationship between two organisms belonging to same or different species in which both are benefitted from one another.

For example - E.coli bacteria, present large intestines of human, gets food and place to live in our digestive tract. In return, the bacteria produce vitamin K, which make it harder for other disease causing bacteria to establish in our system.

Thus, option C) is the right answer.
