Answer;
-The vmax for the reaction would probably be decreased.
Explanation;
- Vmax is the rate of reaction when the enzyme is saturated with substrate is the maximum rate of reaction. The relationship between rate of reaction and concentration of substrate depends on the affinity of the enzyme for its substrate.
-Km is the concentration of substrate which permits the enzyme to achieve half Vmax. An enzyme with a high Km has a low affinity for its substrate, and requires a greater concentration of substrate to achieve Vmax.
-The velocity of enzyme reaction increases when temperature of the medium is increased; reaches a maximum and then falls (Bell shaped curve). The temperature at which maximum amount of the substrate is converted to the product per unit time is called the optimum temperature. Temperature is increased, more molecules get activation energy, or molecules are at increased rate of motion. Their collision probabilities are increased and so the reaction velocity is enhanced.
Answer:
Excertion
Explanation:
The process of removal of waste produced in the cells of living organism is called excretion.
Answer:
A neuron receives stimuli consisting of the response of thousands of neurons. Synapse is the signals entering the neuron via junctions called. The role of the synapses are to modulate the signal strength and determine the input signal is either excitatory, promoting the neuron to fire, or inhibitory, tending to prevent the neuron from firing.
At the axon hillock the neuron integrates the inputs and if this total is excitatory then the neuron fires. Although this brief description leaves out much of the complexity, it is still remarkable that out of this web of electrochemical firing units, emerges our very conscious.
