Animal cells are unique in that they do not exhibit cell walls.Plant cells exhibit very stiff pecto-cellulosic walls, notably because of the presence of cellulose microfibrils, the stiffness of which compares to that of steel.
A fully functioning enzyme molecule is fold into a complex
three-dimensional shape and this structure determines the specific type of
molecules it interacts with during a reaction. Each functioning enzyme molecule
has a particular structure to bind <span>with a high degree of specificity to one or a few molecules
and to carry out its function. Therefore, cellular function is directly
associated to its structures.</span>
Answer:
A fertilized egg cell is a single cell that can develop into one or more specific types of cells in the body. These cells include neurons, blood cells, skin cells, muscle cells, and many others. This process involves two major steps: differentiation and specialization.
During differentiation, each of the many types of cells in the body has to be developed separately. For example, skin cells have to differentiate into hair follicles, sweat glands, sebaceous glands, and so on. The developing brain cells must differentiate into a specific set of brain cells (neurons) that make up the cerebral cortex. During specialization, each of these specialized cells becomes specialized for its specific function. For example, skin cells specialize to form keratinocytes, which form the outer layer of our skin. Neurons specialize to make connections with other neurons in the brain. Blood cells specialize to carry oxygen throughout the body.
The process of differentiation and specialization is continuous, as new cells are constantly being created and old ones are constantly dying off. This continuous process of change is what allows the body to grow and develop throughout life.
Explanation:
My own original work.
When the cell gains glucose, the process of glycolysis occurs and then the glucose is broken down into pyruvate.
Now, in pyruvate processing, Acetyl CoA is produced and used in the Krebs Cycle.
During that process, NADH and FADH2 are made and go into the electron transport chain. That is where water and ATP are made.
