Three characteristics of enzymes​

Biology
2 answers:
natita [175]3 years ago
8 0

Enzymes are biological catalysts. They speed up reactions although they are not changed in the reaction. Enzymes are proteins, and therefore are folded chains of amino acids with a specific shape. This shape is determined by the sequence of amino acids held together by bonds, for example Hydrogen bonds. Enzymes speed up reactions by bringing reactants together and reducing the activation energy required to start the reaction (enzymatic reaction).

Enzymes are specific: they have a specific shape, therefore only a certain substrate will fit its active site. There are two theories of enzyme action: Lock and Key and Induced Fit.  The lock and key theory states that only a certain substrate will fit a certain active site, just like a key fits a lock. Induced Fit, likewise, states that enzymes wrap around substrates, attracted to each other by opposite charges, forming an enzyme substrate complex.

1)Enzyme is a protein. The main material of an enzyme is protein
2)It is easily influenced, by environmental change. Environmental factors include temperature, pH, and inhibitor.
3)It acts as catalyst The enzyme functions in accelerating chemical reaction, but the enzyme itself does not change after the reaction ends.

Explain why germinating seeds were used in this investigation cellualr respiration
Anna35 [415]

Explanation:

As oxygen is consumed to provide energy, germinating seeds release carbon dioxide. ... HYPOTHESES: The experimental hypothesis is that germinating seeds will show a greater rate of respiration than control glass beads. Additionally, that at higher temperatures, the rate of cellular respiration in the seeds will increase.

Determine whether the following actions are harmful to the environment or help to conserve the environment.
Temka [501]

Coach Luke encourages his football team to wear biodegradable sneakers. The sneakers can be buried in the ground when they are worn out, and after many years, they will decompose like a plant. This condition conserves the environment.  

<h3>What do you mean by Environment?</h3>

An environment may be defined as anything which is present in the surroundings of living entities that is either biotic or abiotic factor.

Chef Sonia uses disposable, nonbiodegradable kitchen towels in her kitchen. She uses them for everything from cleaning up spills to wiping her hands. She ends up using about two rolls in a month. This condition harms the environment because the towels are nonbiodegradable in nature.

The last situation conserves the environment because it utilized solar panels for energy production which is efficient in cost as well as helpful for the environment.

Therefore, each situation is mentioned above.

gizmo_the_mogwai [7]

Answer:

d) They would bind glucocorticoids, and initiate estrogen-dependent synthesis

Explanation:

Both Glucocorticoids and estrogens Hormones have important but distinct physiologic functions. These two hormones belongs to the two classes of steroid hormones. Both of these hormones binds to their specific receptors.

DNA binding domain is the domain that after activation by external factors such as hormones express the specific proteins by binding to specific region of the DNA.

As DNA binding domain of a glucocorticoid receptor is altered with DNA binding domain of estrogen receptor so it means binding site of the glucocorticoid hormone for glucocorticoid receptor remains the same and binds to glucocorticoids but on binding it activates the estrogen DNA binding domain which further binds to specific region in the DNA which initiates estrogen dependent synthesis.
