Answer:
c. they enter an electron transport chain.
Explanation:
The chlorophyll in leaves of plants undergoing photosynthesis is made up of two pigments ; these are the primary pigments and the accessory pigments. The latter are arranged around the primary pigments. These two pigments are arranged in chlorophyll to form photo systems i and ii. The photosystems serves as the reaction centers of chloroplast. <u>Basically the accessory pigment absorbs photons of energy and sends this to the primary pigments.</u>
When photons of light is absorbed by the chlorophyll of the leaf. The electrons in the chlorophyll are excited, and therefore move to higher energy levels. At this stage they are said to be activated. This process is called Photoactivation.
However, instead of the excited electrons to return to the photo- systems so that the acquired energy is lost as heat to the surroundings, these electrons are trapped by electron acceptors and are passed to the electron transport chains. These chains of electrons generate proton motive force PMF, for pumping protons across the thylakoid membranes , down into the thylakoid for the synthesis of ATPs by ATPase synthase; through Chemiosmosis.
The ATP is needed in Calvin's Cycle for Carbohydrates synthesis.
Explanation:
Trophic levels is known as feeding levels in an ecosystem.
Trophic levels is any of the stages involved in the food chain. In an ecosystem, the trophic levels begins with the producer which provides foods from inorganic sources.
- Consumers at all levels feeds on the food produced by the producers. Some consumers feeds on other consumers.
Neurons that carry information away from the central nervous system are called motor (or efferent) neurons.
A car needs to be fueled before it can set in motion to posses a given amount of kinetic energy.
<h3>What is energy?</h3>
Energy is the capacity of doing work. In physics, there exist different types of energy; among which are follows:
- Kinetic energy: Kinetic energy can simply be defined as that energy a body posses due to its motion
- Potential energy: , On the other hand, potential energy is the energy a body has due to its relative position.
Other forms of energy include:
- Solar energy
- Nuclear energy
- Mechanical energy
So therefore, a car needs to be fueled before it can set in motion to posses a given amount of kinetic energy.
Therefore, kinetic energy is the energy which allows a car to be fueled before it can set in motion .
