Answer:
This signifies that the protein primarily comprises multiple polypeptide chains connected together with the help of disulfide bonds. The enzymes may be found in the form of dimers, trimers, or tetramers. Various examples of dimers, trimers, and tetramer proteins are known, of them, NEMOs dimers are considered to be held by disulfide bonds.
Thus, it can be hypothesized that the enzyme under examination is a multimer held in combination by disulfide bonds, with each comprising catalytic sites. On breaking of disulfide bonds, the enzyme dissociates into its many single units.
This illustrates the reduction in catalytic activity. Each active site in a single unit will work, however, at a gradual rate. This also shows detection of multiple globular proteins after disulfide reduction.
One characteristic of life is that living things have different levels of organization
-They have both molecular and cellular organization
- They must have the ability to organize simple substances into complex ones.
- They organize cells at several types of levels, namely:
(a) Tissue- a group of cells that perform a common function
(b) Organ - A group of tissues that perform a common function.
(c) Organ system- a group of organs that perform a common function.
(d) Organism- any complete living thing.
The eubacteria is photosynthetic, like a plant is.
Answer:
Pulmonary fibrosis is a disease that affects the lungs. The lung tissue becomes damaged and scarred which causes it to be thickened and stiff.
The condition pulmonary fibrosis is caused by the replacement of elastic fibers in the lung with inelastic collagen fibers. This decreases the lungs’ ability to stretch outwards.
Pulmonary fibrosis however mainly affects inspiration because the lungs cannot stretch to increase volume while during expiration stretching of the tissues doesn’t happen so it doesn’t affect the process.
Answer:
Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.
