Which products of photosynthesis does your body break down to be used for cellular respiration?

dedylja [7]

Answer:

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.

hope this helps!

In photosynthesis, the reactants are more stable than the products. However, both the products and reactants are stable. Therefo

My name is Ann [436]

Answer:

A.) Absorb and store

Explanation:

The reaction for photosynthesis is:

$6CO_{2}+ 12H_{2} O$ → $C_{6} H_{12} O_{6} +6H_{2} O$ (reaction conditions: light and chlorophyll)

carbon dioxide + water → glucose + water

This means light energy is absorbed and stored as sugar molecules and energy for the plant

Therefore, the photosynthesis reaction will  absorb  energy and  store  it in the chemical bonds.

A 1.00-L sample of carbon tetrachloride has a mass of 1.58 kg. What is the density of this substance in g/cm3?

Hoochie [10]

Answer:

1.58gcm⁻³

Explanation:

Given parameters:

Volume of sample = 1.00L

Mass of sample = 1.58kg

unknown:

Density of the sample

Solution:

The density of a substance is expressed as its mass per unit volume.

The units of the parameters are given for volume as liters and for mass as kg.

We need to convert to cm³ for volume and into g for the mass:

1L = 1000cm³:

Therefore, the volume of the sample is 1000cm³

For the mass:

1kg = 1000g

1.58kg gives 1.58 x 1000g = 1580g

The density of the sample will be:

Density = $\frac{mass}{volume}$

Density = $\frac{1580}{1000}$ = 1.58gcm⁻³
