Answer:
The Cell membrane is the main source of wnergy for the cell
Explanation:
Its the ATP. Cells make use of a molecule called adenosine triphosphate, or ATP, as a source of fuel.
Answer:
True.
Explanation:
Trees are responsible for stabilizing carbondioxide concentration in the environment because carbondioxide is used by the plants in the process of photosynthesis. So when we cut down trees, the carbon which is present inside the body of plants also emitted in the form of carbondioxide by the process of decomposition. Decomposers such as bacteria and fungi etc are responsible for the release of carbondioxide.
Answer:
False
Explanation:
Uncertainty is one of the biggest parts of science.
There are many things that have been uncertain in science, and there are still lots of things for us to discover.
Uncertainty in science is the reason why experiments are done and why hypotheses are made.
Uncertainty IS a part of science, and is a very important part, so the statement is false.
Answer:
Energetic electrons that provide the energy for the production of most of a cell"s ATP are carried to the electron transport system by reduced co enzymes such as NADH,FADH2.
Explanation:
During glycolysis and TCA cycle maximum redox reaction utilizes either NAD+ or FAD .NAD+ and FAD are used as co enzymes which get reduced to NADH and FADH2 during various re dox reactions of aerobic respiration.
But this reduced co enzymes should be converted to active form and to do this the reduced co enzymes such as NADH and FADH2 enter into electron transport chain to donate electrons thus converting them into their active form.
