Question

a). The logarithmic phase of microorganisms in an idealized growth curve seen in the environment is only transient.

True or false

b) Archaeoglobus is a hyperthermophilic bacterium.

True or False

c) ATP was a requirement for the first prebiotic cells.

True or False

Answer 1

a) TRUE:-  The logarithmic growth phase cannot continue indefinitely, however, because the medium is soon depleted of nutrients and enriched with wastes.

b) TRUE:- Archaeoglobus are hyperthermophiles that can be found in hydrothermal vents, oil deposits, and hot springs. They can produce biofilm when subjected to environmental stresses such as extreme pH or temperature, high concentrations of metal, or the addition of antibiotics, xenobiotics, or oxygen

c) TRUE:-  All the cells use ATP as their source of metabolic energy to drive the synthesis of cell constituents and carry out other energy-requiring activities, such as movement. The mechanisms used by cells for the generation of ATP are thought to have evolved in three stages, corresponding to the evolution of glycolysis, photosynthesis, and oxidative metabolism.
