Answer:
Experiment 4. Relaxed, the drug will stop the calcium so that it does not act on the troponin
Experiment 5. Contraction: In order for the muscle to relax, the actin and tropomyosin union must occur.
Experiment 6. Relaxation: the release of the actin-myosin complex occurs with consumption of ATP, thus it slides and generates contraction, by adding a hydrolyzable analog, this reaction is avoided giving rise to a prolonged actin-myosin binding which leads to relaxation while last effect.
Experiment 7. Ca2 + Contraction is very necessary so that during muscle contraction troponin can be extracted.
Answer:
a. add more of the enzyme.
Explanation:
Enzymes speed up the rate of reaction by lowering the activation energy for the reaction. They are not used themselves in the reaction. They are specific to substrate molecule. Substrate molecule binds to enzyme's active site and they undergo the reaction to form the product and release back the enzyme.
Rate of reaction depends on both substrate and enzyme concentration. Maximum rate of reaction is reached when all the active sites of enzyme molecules have been occupied by the substrate molecules which means that they are saturated. If more substrate is added at this point it wont have any effect on rate of reaction since there are no free active sites. Hence more enzyme is required to be added so that extra substrate can be utilized and rate of reaction can further be increased.
Answer:
The answer is the 4th one.
Explanation:
Observing the data, we can see a relationship between the amount of light exposure and the amount of bubbles (oxygen) produced in photosynthesis.
As the distance from the light source increases, we see the number of bubbles decrease. We can establish that semi-linear relationship, therefore eliminating option 2.
Option 3 is not directly related to the data in the table, but rather about the inner workings of photosynthesis.
That leaves us with option 1 and option 4. They are both correct, and can be interpreted from the data provided; however, option 1 is vague, and does not use specific data points, only a relationship derived from them.
Therefore, by elimination of options, we can clearly see the correct option is the 4th one.
Explanation:
Viral protein 1 (VP1) is a surface-exposed pentameric protein that makes up the viral icosahedral capsid through the interconnectivity of 72 VP1 pentamers and is the viral attachment protein for all known polyomaviruses,.
The base pairs are put into different orders and these orders code for different amino acids.
