Answer:
Many cellular processes use similar mechanisms to achieve different goals.
Explanation:
<em>Metabolic pathways are series of enzyme-catalyzed reactions. Enzymes interact to remove and add phosphate groups to molecules or to move protons across a membrane. The same as in cell signalling, where the receptor proteins interact with specific molecules and often remove or ad phosphate groups. The phosphorylation of receptor proteins is very close to the process steps in metabolic pathways but with a very different function. </em>
<em>In metabolism phosphorylation is a method of transferring energy, in cell signalling it transmits information.</em>
The formation of macromolecules from triose phosphate is likely anabolic and would be coupled to ATP -> ADP.
Anabolic is a group of metabolic pathways that builds compounds out of smaller building blocks. These reactions, which are often referred to as endergonic processes, demand energy. Catabolism is the breakdown component of metabolism, whereas anabolism is the building component. Typically, anabolism and biosynthesis go hand in hand. Anabolism can be seen in the growth of muscle mass and the mineralization and development of bones. Proteins are broken down into amino acids during catabolic events, as are glycogen and triglycerides into glucose and fatty acids, respectively. Fundamentally, catabolism entails disassembling complex molecules to produce energy that may be utilised by the organism. By building larger, more complex molecules from smaller, simpler ones, anabolism is the exact reverse of catabolism. The body typically stores them for later use.

<span>As the pollen tube penetrates the ovule, it releases two sperm cells. As in gymnosperms, the ovule becomes a seed, encasing the embryo and endosperm in a seed coat. But unlike gymnosperms, in angiosperms the ovary containing the ovules develops into a fruit after fertilization.</span>
Answer:
Multiple Sclerosis is an inflammatory disease in which myelin sheath of nerve cells of brain and spinal cord are damaged.
Explanation:
Cause:- (Exact cause of inflammation is not known)
- But damage is caused due to attack by autoimmune cells or antibodies against myelin sheath.
Types of tissues attack:-
- Oligodendrocytes and myelin sheath is damaged and stripped away from axon and the process is known as demyelination.
- Myelin sheaths are made up of fatty tissues and help in transmission of electric impulse.
Result of immune system attack:-
- Damaged myelin sheath stop forming whIte matter of central nervous system.
- Hence disrupt coordinating communication between different brain regions.
Signs and symptoms:- vary from person to person
- Diminished eyesight.
- Disrupt motor coordination.
- Weak sensory perception.
- Fatigue and dizziness.
- Speech disorder.
- Muscle weakness and spasticity.
- Difficulty in urination and stool.
Diagnosis and treatment:-
- Diagnosis include MRI T2 findings and cerebrospinal fluid specific oligoclonal bands.
