Answer:

It combine with hydrogen and two electrons form water.

It is necessary for our breathing.

Explanation:

Oxygen during cellular respiration is very important.

It combine with hydrogen and two electrons form water.

It is necessary for our breathing. cellular respiration take place effectively in the presence of oxygen and produced more ATP.

There are two types of respiration:

1. Aerobic respiration

2. Anaerobic respiration

Anaerobic Respiration

It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.

Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide

Aerobic respiration

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.

Glucose + oxygen → carbon dioxide + water + 38ATP

An event lasts 4 hours and 20 minutes. How long did the event last in seconds?

daser333 [38]

The event last in 15,600 seconds.

Answer: Option B

<u>Explanation:</u>

We know that there is 60 seconds in one minute i.e., 1 minute = 60 seconds

There is 60 minutes in one hour. i.e., 60 minutes = 1 hour.

Given : An event lasts 4 hours and 20 minutes

4 hours contains 240 minutes,

$4 \times 60=240 \text { minutes }$

When the above expressed in seconds,

$240 \times 60=14400 \text { seconds }$ ------>eq. 1

When 20 minutes expressed in seconds,

$20 \times 60=1200 \text { seconds }$ ------->eq. 2

Adding both eq. 1 and 2, we get

4 hours and 20 minutes = 14400 + 1200 = 15600 seconds

Which describes the complex carbohydrate cellulose?

FromTheMoon [43]

Like starch, cellulose is a complex carbohydrate made up of many molecules of glucose linked together. But unlike starch, plants do not use cellulose to store energy. Instead, plants use cellulose as a structural molecule. It forms the cell wall that gives plant cells shape and support.
