Without enzymes, proteins that control the speed of chemical reactions in your body would take place too slowly to keep you alive. For example, the enzymes in your gut break down large molecules into smaller ones.

to act as a catalyst in chemical reactions

This is the answer because an enzyme speeds up the rate of the reaction, as a catalyst also does this job.

Explanation:

Photosynthesis and cellular respiration are connected through an important relationship. This relationship enables life to survive as we know it. The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis:

Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O

Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O2

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration. We breathe in that oxygen, which is carried through our blood to all our cells. In our cells, oxygen allows cellular respiration to proceed. Cellular respiration works best in the presence of oxygen. Without oxygen, much less ATP would be produced.

Cellular respiration and Photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere.

Bumek [7]

A patient that has a serious lung infection, the patient's sputum has been taken for sample and the lab technician stated that the lab isolated a bacterium that has no peptidoglycan. The microbe could possibly be a mycoplasma pneumoniae. A mycoplasma pneumoniae has no peptidoglycan cell wall, meaning, the patient has the microbe of mycoplasma peneumoniae.

umka21 [38]

Answer:

Alternating the compressor role every 2 minutes.

Explanation:

High-quality CPR is essential to help the person survive after getting into cardiac arrest.

In the high-quality CPR, two rescuers are involved and they switch positions in the CPR after every two minutes.

By switching their positions the two rescuers alternate in this high-quality CPR to give the chest compressions.

This switch is essential to reduce the fatigue faced by the rescuer.

How are nucleus and chloroplasts different?

Kamila [148]

Answer:

Chloroplasts are endosymbiotic descendants of photosynthetic cyanobacteria-like prokaryotes that were incorporated into cells more than a billion years ago.

Explanation:

Photosynthesis converts electrochemical energy from light into sugars and acts as the carbon source of the cell.
