¿Que dos moléculas necesitan las plantas para la fotosíntesis?

Biology
1 answer:
viktelen [127]3 years ago
3 0
Para realizar la fotosíntesis las plantas necesitan varios elementos que se encuentran en el medio ambiente.

Energía luminosa: impacta sobre las hojas y es absorbida por el pigmento fotosensible de la planta, la clorofila.
Agua: La fotosíntesis requiere un suministro constante de agua. Ésta llega a las hojas a través de las raíces y tallos.
Clorofila: Pigmento de color verde contenido en el cloroplasto. Se encarga de la absorción de la luz, para llevar a cabo la fotosíntesis.
Dióxido de carbono: Es absorbido por unos minúsculos poros, llamados estomas, en la parte inferior de la hoja.
Oxígeno: subproducto de la fotosíntesis. Sale de las hojas hacia el exterior a través de lasestomas.

Explain how the equations for photosynthesis and respiration are related. Identify each as being either catabolic or anabolic re
larisa [96]

Answer:

An anabolic reaction can be described as a reaction in which reactants join to form products. In the process of photosynthesis, carbon dioxide and water molecules join to build up glucose molecules hence, it is an anabolic reaction.

The catabolic reaction can be described as a reaction in which large molecules are broken down into smaller substances. In cellular respiration, glucose is broken down into carbon dioxide and water. Hence, cellular respiration is a catabolic reaction.

The equations of photosynthesis and cellular respiration are exactly opposite to one another. Hence, holding a connection. The products of photosynthesis are the reactants of cellular respiration and vice versa.

In humans, the quadriceps muscle is a skeletal leg muscle under voluntary control. As such, it contracts in response to signals
Masja [62]

Answer:

The correct answer is - operation of reflex arc.

Explanation:

The reflex arc is a unique and special type of neural pathway that starts with a sensory neuron and ends with a motor neuron. In this operation sensory neuron acts as the receptor and motor neuron is effector. This type of neural circuit helps in faster response.

Voluntary muscles like quadriceps muscle are normally in control voluntarily however, such muscle may contract involuntary due to reflex arc. This type of contraction takes place before the signal has even reached the brain.

In this response the sensory neuron takes the signal to the spinal cord and then motor neuron to the effector muscle for faster response.

Thus, the correct answer is - operation of reflex arc.
