Question

In the following list, write the name of the space or membrane where each metabolic process takes place.

Choices: Inner membrane, outer membrane, periplasm, matrix, cytoplasm

Glycolysis in Gram-negative bacterium Glycolysis in a human cell Citric acid cycle in Gram-negative bacterium Citric acid cycle in a human cell Electron transport in a human cell Electron transport in Gram-negative bacterium Oxidative phosphorylation in a human cell Oxidative phosphorylation in Gram-negative bacterium

Answer 1

1.Glycolysis in gram - negative Bacteria :-   Cytoplasm

Reason : Glycolysis occur s in the cytoplasm and makes a few ATP and NADH

2. Glycolysis in Human cell - Cytoplasm

Reason :- Glucolysis takes place in the cytoplasm.

3. Citric acid cycle in gram negative bacterium - Cytoplasm

Reason:- Citric acid cycle happens in the mitochondria of euraryotic cells, but bacteria don't have mitochondria , so we're still in the cytoplasm.

4.Citric acid cycle in Human cel - Matrix

Reason ;- The citric acid cycle takes place in the matrix of the mitochondria.

5.Electron transport in a human cell :- Inner Membrane

Reason :- Electron transport in human cells occurs in the inner membrane of mitochondria.

6,Electron transport in gram negative bacterium :- Outer membrane

Reason ;- Electron transport in gram negative bacterium occurs in outer cytoplasmic membrane.

7.Oxidative phosphorylation in a human cell :- Inner membrane

Reason :- Oxidative phosphorylation takes place in the inner mitochondrial membrane.

8.Oxidative phosphorylation in gram negative bacterium :- Inner membrane

Reason :- .Oxidative phosphorylation in gram negative bacterium occurs inner cytoplasmic membrane.
