Answer:

d) The enzyme changes shape and can no longer speed up the reaction

Explanation:

Enzymes aare protein in nature therefore sensitive to changes in temperature. Most enzymes have an optimum temperature ranging from 35-40°c. As the temperature increases, optimum temperature is reached where the rate of reaction is maximum. Temperatures above 40-63°c denatures the enzymes making them non effective thus the reaction decreases sharply.

LiRa [457]

Answer:

The observation that could be made in regards a neon light placed in one evacuated (airless) chambea r, and battery powered radio placed in a second evacuated chamber, switched on at the same time by remote control, is that they are managed as capacitors.

Explanation:

Capacitors, also known as condensers, store energy and, we can also see them in the sky, they are the clouds.

Capacitors are made of two electrical conductors, separated by an insulator, when you add electrical energy to a capacitor you are charging a capacitor, the opposite is known as discharging.

Which major processes were needed for the origin of life on Earth?
Anit [1.1K]

Answer:

The conditions of the early Earth were not at all feasible for the survival of life. The primitive conditions of the earth had a very heated environment. There was not enough amount of free oxygen present. The only oxygen that was found at that time was in the water molecules of in other molecules and hence there was no free oxygen. Some prokaryotes, which were able to survive in hydrothermal vents were able to survive in these primitive conditions.

Monoamine oxidase inhibitors cause an antidepressant effect by
uranmaximum [27]

Answer:

C. inhibiting the breakdown of neurotransmitters in the brain

Explanation:

Monoamino oxidase (MAO) facilitates the break down and removal of neurotransmitters like nor-epinephrine, epinephrine, serotonin in brain which have excitatory effects on neurons. When these neurotransmitters are degraded by MAO, this would lead to decreased excitatory level of neurons and it will become less functionable as seen in most of the patients suffering from depression, panic disorders, social disphobia and some neurodegenerative disease.

Monoaminooxidase Inhibitors prevents the degradation of above mentioned neurotransmitters which leads to increasing their levels and concentration which allows them to work and influence on neurons effected by depression.
