What is the process of photosynthesis​
statuscvo [17]

The process of photosynthesis is the synthesis of food molecules from inorganic compounds using energy from sunlight.

<h3>WHAT IS PHOTOSYNTHESIS?</h3>

Photosynthesis is the process whereby green plants obtain their food (glucose) in the presence of sunlight as an energy source.

Photosynthesis takes place in two stages namely;

  • Light dependent reactions
  • Light independent reactions

Photosynthesis combines carbon dioxide and water as reactants as follows:

6CO2 + 6H2O = C6H12O6 + 6O2

Therefore, the process of photosynthesis is the synthesis of food molecules from inorganic compounds using energy from sunlight.

When cells communicate by the signaling process, one cell produces a _________________BLANK that must be received by the _______
velikii [3]

Answer:

1. Signaling molecule

2. Signaling receptors

Explanation:

Hormones, growth factors, neurotransmitters, etc. serve the function of signaling molecules for cells. These molecules are released by one cell and bind to the receptors present on/in the target cells to elicit the desired response. Thereby, the signaling molecules serve in cell-cell communication.

For example, insulin hormone synthesized and released from beta cells of pancreas binds to its cell surface receptors present on the surfaces of liver cells and muscle cells to stimulate the uptake of the glucose from the blood.  

Likewise, neurotransmitters released from the presynaptic neuron bind to receptors present on the membrane of postsynaptic neuron and serve to carry the nerve impulse to the postsynaptic neuron.

In what two ways are active transport proteins similar to enzymes
Ksju [112]
  1. They change conformation/shape when the right molecule bind in their active site.
  2. They enable reactions to proceed ‘downhill’. For enzyme, when the reactants are more than the products, the reaction proceeds to the right of the reaction. Career proteins also carry molecules down their concentration gradient.
  3. Both career proteins and enzymes are not denatured  during the process of their biological activity
