Catalysts work by providing an alternative mechanism involving a different transition state and lower activation energy. Consequently, more molecular collisions have the energy needed to reach the transition state. Hence, catalysts can enable reactions that would otherwise be blocked or slowed by a kinetic barrier.

Answer:

A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism. Enzymes are proteins that act as catalysts in biochemical reactions.

A substance synthesized at the cell body must undergo ______ transport to reach the synaptic knobs.
cricket20 [7]

The cell body must undergo Anterograde transport to reach the synaptic knobs.

The synaptic feature is to transmit nerve impulses between two nerve cell neurons or among a neuron and muscle cellular. Synapses connect one neuron to every other and are thus liable for the transmission of messages from the nerves to the mind and vice versa.

Synapses are a part of the circuit that connects sensory organs, like those who come across aches or touch, within the peripheral frightened gadget to the mind. Synapses connect neurons inside the mind to neurons inside the rest of the frame and from those neurons to the muscle tissues.

Synaptic transmission is the method at synapses by way of which a chemical sign is launched from one neuron and diffuses to other neurons or goal cells where it generates a sign which excites, inhibits, or modulates mobile hobby.

PLEASE HELPP!! match the word with the definition
alexira [117]

Answer:

A. Miosis

B. DNA molecule

C. Body cells

D. phenotype

E. Recessive traits

F. genotype

G. Punnet square

H. nondisjunction

I. mitosis

J. sex cells

Explanation:

In meiosis cell division, a parent cell divides into four daughter cells whereas in mitosis, one cell divides into two daughter cells. If change occur in DNA molecules, mutation occurs. Phenotype refers to physical characteristics of an organism whereas genotype indicates genetic characteristics. Recessive traits only appears when the organisms have same traits or allele. Somatic cells is known as body cells whereas gametes is known as sex cells.

Helo! i was wondering if anyone could help me of these two questions for biology?
Rom4ik [11]

1) A 2) B

Explanation:

Enzymes are catalyst, meaning that they could be use in several reaction and they speed up any chemical reaction rate. So knowing this, when the animal have more enzymes it will react more quickly with the food, making it digest the food more quickly.

Hope the help, cheers

11. What is systolic pressure?
Romashka-Z-Leto [24]
When you take blood pressure, it is expressed in a fraction. The top number of that fraction is systolic pressure- the amount of pressure in your arteries during contraction of your heart muscle... I hope this helped! :)
