The various processes of cellular respiration take place in the cytoplasm and mitochondria. by moving between these different chemical environments our cells are able to generate atp more efficiently. what compartments do gylcoysis, the krebs cycle and the electron transport chain occur in?

Glycolysis: Cytoplasm

Kreb's cycle: Mitochondrial matrix

Electron transport chain: Inner mitochondrial membrane

Explanation:

Glycolysis is the first stage of cellular respiration and occurs in the cytoplasm. It does not require the presence of oxygen. Glycolysis enzymes are present in the cytoplasm. Pyruvate formed by the glycolytic breakdown of glucose enters the mitochondrial matrix and undergoes oxidative decarboxylation to form acetyl CoA. Acetyl CoA enters the Kreb's cycle. All the reactions of Kreb's cycle occur in the matrix of mitochondria.

The reducing powers NADH and FADH2 enter the electron transport chain to become oxidized again. The electron transport chain consists of a series of electron carriers embedded in the inner mitochondrial membrane.

answer: blah

explanation:

bc blah

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
