Answer:
The archaea and the bacteria both are prokaryotes. However, the genetic makeup of the archaea is more similar to the eukaryotes. Moreover, they have differences, in their metabolic pathways, genes and the enzymes possessed by them.
Explanation:
The differences between Archaea and bacteria:
1. The cell wall of the bacteria consist of peptidoglycan, while the cell wall of the archaea consist of pseudo-peptidoglycan.
2. The bacteria are capable of spore formation, which can lie dormant for long periods of time until a suitable condition is found for their growth. The archaea are not known to form such spores.
3. The genes of the archaea are more similar to the eukaryotes than the bacteria.
4. The bacteria are found everywhere where the living conditions are suitable (soil, air, living beings, non-living things). the archaea are capable of surviving in extreme conditions (hot springs, salt brine).
5. The bacteria use the process of glycolysis and follows Kreb's cycle for glucose break-down. The archaea do not undergo glycolysis or Kreb's cycle.
Answer:
-20 kcal/mol (It stays the same)
Explanation:
Enzymes will reduce the Gibbs free energy of activation, but will neither increase or decrease the free energy of reaction.
Enzymes means of activity is by decreasing the activation energy (Ea or ΔG✳) for a reaction. This in turn raises the reaction rate.
Free energy of reaction
= free energy of product - free energy of substrate
The free energy of the product remains constant even without the enzyme. Hence, the enzyme would show no effect on the free energy of the reaction.
The attached image shows the effect of changes in enzyme concentration on the free energy.
Answer:
Cell is the basic , functional unit of life
An atom is the smallest unit of ordinary matter that forms a chemical element .
<span>The organic chemicals that help
cell membranes to conserve internal fluids are the phospholipids. They are
composed of fatty acid, glycerol, phosphate group and a polar molecule. The phosphate
group and polar head region of the phospholipids is attracted to water while
the fatty acid is repelled by water. They are a major component of the cell
membrane in which it encloses the organelles of the cell. It also limits what
enters and exits the cell because of its two heads.</span>
