Which of the following is present only in the Gram negative bacteria and not found in Gram positive peptidoglycan space plasma membrane Which of the following can act as (an) electron acceptor (s) in bacteria when there is not enough NO_3 pyruvic acid SO_4 both NO_3 and SO_4 NO_3 pyruvic acid and SO_4 Where is the most ATP generated for eukaryotic cells? in the cytoplasm in the cytoplasmic membrane In the out membrane of mitochondria in the mitochondrial matrix at the ribosomes In aerobic respire ion. the initial electron donor is. NADPH NAOH NAD NADD H_2O Which of the following is present in both Gram positive and gram negative bacteria\"?. periplasmic space my colic acid LPS Teichoic acid peptidoglycan NAD^+ + H^+ rightarrow NADH This reaction is best described as: hydrolysis condensation oxidation reduction dehydration synthesis If you haw isolated a cell that has no visible nucleus. You can assume that the cell Golgi complex mitochondria ribosomes endoplasmic reticulum all of the above Which of the following when metabolized by the cell can form the largest amount Succinate Acetate pyruvic acid

c. periplasmic space----answer

d. plasma membrane

===========================================================================

46. which of the following can act as (an ) electron acceptor (s) in bacteria when there is not enough oxygen

Answer Both sulfate (SO 4 ^2-), nitrate (NO3

==================================================================================

47. where is the most atp generated for eukaryotic cells

Answer in the mitochondrial matrix

==================================================================================

48 . in aerobic respiration the initial electron donor is

NADH

In aerobic respiration, the initial electron donor in the respiratory electron transport chain is NADH

==================================================================================

49 .answer ; peptidoglycan

========================================

the outer membranes of the Gram-negative microscopic organisms give a particular obstruction to outside particles and in this manner keep the loss of metabolite-restricting proteins and hydrolytic chemicals (nucleases, antacid phosphatase) found in the periplasmic space. The periplasmic space is the area between the external surface of the inward (plasma) layer and the internal surface of the external film . Along these lines, Gram-negative microscopic organisms have a cell compartment that has no proportional in Gram-positive living beings.

=============================

Numerous H2-oxidizing microscopic organisms (i.e., microorganisms that can develop utilizing H2 as a vitality source/electron benefactor) can utilize O2, NO3-1 or SO42-as an electron acceptor. However microscopic organisms that utilization NH4+, H2S, or Fe+2 as a vitality source utilize O2 only as a terminal electron acceptor

=================================================================

In the Gram-positive Bacteria, the cell divider is 5-80 nanometers in thickness and comprising of a few layers of peptidoglycan.

In the Gram-negative Bacteria the cell divider is generally thin (10 nanometers) and is made out of a solitary layer of peptidoglycan encompassed by an external film.
