<u>Answer: </u>
Four stages involved in cellular respiration does not function independently. Instead, they Dependent on each other.
<u>Explanation:</u>
Four stages in cellular respiration involves Glycolysis, link reaction, Kerbs cycle, electron transport chain.
Glycolysis is the initial stage in cellular respiration. In this stage, the glucose present in the cytoplasm is broken down into 2 molecules of Pyruvate.
The second stage is the link reaction or the bridge reaction. In this stage, the pyruvate produced in the first stage is pumped actively into the mitochondria. Now the pyruvate is converted into acetyl group by removing one molecule of and two molecules of . This acetyl group combines with CoA Enzyme to produce acetyl CoA.
In the Kerb’s Cycle, the Acetyl CoA combines with oxaloacetate to form a 6 carbon atom compound.
Now in the electron transport chain stage, the energy released by the electrons are used to pump the hydrogen that was removed in the previous stages.
Thus the by-product of one stage is used as the source in another stage. Hence the cellular respiration process is not independent.
Answer:
a) Thigmotropism
b) Phototropism
c) Gravitropism
Explanation:
A) the turning or bending of a plant or other organism in response to a touch stimulus. example: the folding movement of the Mimosa pudica leaflets, can be considered as an example of thigmonastism.
B) the orientation of a plant or other organism in response to light, either towards the source of light ( positive phototropism ) or away from it ( negative phototropism ).example: Sunflower is a highly phototropic plant. They grow towards the sun and are also seen tracking the movement of the sun throughout the day. That is, the flower keeps changing its direction with the movement of the sun. Sunflower requires more light for its growth and survival.
C) The gravity-directed growth process, called gravitropism, dictates upward shoot growth to ensure a proper positioning of the leaves for efficient photosynthesis and gas exchange. example: tree has fallen over and due to gravitropism exhibits this arched growth.
Respiration is the chemical reaction that break down nutrient molecules in living cells to release energy .
in humans and other living organisms except plants, our cells need energy ATP for muscle contraction and for cell division to repair damaged tissues and growth ,also for active transport which involves movement of molecules across a cell membrane against a concentration gradient.
The results showed that the atoms were mostly empty space but a few particles were deflected.
