Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

Hi I need help ^^

kotykmax [81]

Smoking is one of the major reason of Lung cancer. But one may have cancer even if the individual is not a smoker due to radiation, secondary air pollutants.

<h3> What is cancer?</h3>

Cancer is described as the uncontrolled and abnormal growth of cells in one’s body which are arrested in the growth phase of the cell cycle and multiply rapidly and does not mature like normal cells, cancer is more aggressive form of a tumour.

The following describe the relation of smoking with lung cancer

Cancer is caused by oncogenes activating substances [OAS] some of them causes mutation in the body

These oncogenic substances in the smoke produced while smoking contains nicotine, hydrocarbons, cyclohydrocarbons and various other factors which converts normal cells into cancerous cells

Hence,
smoking
causes
oral
and
lung
cancer

What role does H20 have in cellular respiration

Marizza181 [45]

Answer:

$H_{2}O$ or Water is a very important component of the cellular respiration. However, it does not act in the process of cellular respiration directly, but is produced at the end of the cellular respiration during Oxidative Phosphorylation or Electron Transport System.

Basically, what happens is during the stages ETS, the NADH and $FADH_{2}$ gets converted into NAD and FAD whereas the $H^{+}$ ion accumulates into the inter-membrane space, which then passes through the ATP synthase molecule from the inter-membrane space to the matrix thus, stimulating the ATP synthase molecule to produce ATP the most important product of cellular respiration. This $H^{+}$ ion when enters the matrix gets utilized to form $H_{2}O$ by getting bound to $O_{2}$ . But if no $H_{2}O$ is produced in the final stage and the $H^{+}$ ion gets accumulated in the matrix then the cellular machinery will malfunction and the production of ATP will stop. Thus, by this fact, we know that $H_{2}O$ has a very important role in cellular respiration.
