Chlorophyll molecules are the most abundant pigments in plants that are responsible for collecting light for photosynthesis. Which of the following statements are true? The two main forms of chlorophyll are chlorophyll a and b. These molecules resemble the protoporphyrins in hemoglobin and myoglobin, except these contain Fe+2 rather than Mg+2. They require the presence of accessory pigments such as beta-carotene and lutein in order to function. They absorb light in the blue and red region of the visible spectrum, which is why they appear green.

Option A.

The two types of chlorophyll are chlorophyll A and B.

Explanation:

Chlorophyll is the green pigments present in chloroplast (organelles) that is found in plants which is used for photosynthesis by reacting with carbon dioxide and water to produce carbohydrates. The two types of chlorophyll are; chlorophyii A and chlorophyll B.

Chlorophyll A is the primary photosynthetic pigment that absorb energy from blue- violet light and orange red lights wavelengths.

Chlorophyll B is the accessory pigment to receive energy and transmit it to chlorophyll A. Chlorophyll B absorbs energy from green lights wavelengths.

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.  

i would say the prokaryotic cells the prokaryotic cells are less complex, are usually found only in unicellular organisms and have more limited capabilities than eukaryotic cells.
