Answer:
Explanation:
The structure of a cell membrane is the outer layer of the cell and it contain various cell organelles which are present in both animal and plant cell. It's act as a barrier between the outside environment and cellular content of the cell. It comprises of phospholipid bilayer and integral protein which allow molecules to pass through the membrane and it limits the movement of molecules in the membrane because of it's hydrophobic interior which make the passage of molecules to be selectively permeable.
Answer:
Histidine, Glycine, Glycine, Tyrosine, Glycine
Explanation:
Answer B
The correct answer is: B) 6 CO2 + 6 H2O ? C6H12O6 + 6 O2
Photosynthesis is a process of converting light energy to chemical energy in the form of sugars (carbohydrates). It is performed by plants, some algae and bacteria.
In the reaction of photosynthesis, sun energy combined with carbon dioxide (CO2) and water (H2O), to form glucose (C6H12O6) and oxygen (O2). Photosynthesis consists of two stages: the light-dependent reactions (in thylakoid membrane) where ATP is formed and the Calvin cycle (in stroma) where ATP is used.
Answer:
1. Carbon dioxide
Explanation:
During photosynthesis, autotrophs such as green plants, algae, etc. remove carbon dioxide from the air and incorporate it into complex organic compounds such as glucose. Plants use much of the glucose to produce their own biomass. Heterotrophs feed on autotrophs and obtain these organic compounds from them. Heterotrophs perform cellular respiration during which oxidation of organic compounds produces ATP molecules. The process of cellular respiration returns carbon dioxide to the atmosphere. Autotrophs obtain this CO2 from the air for photosynthesis and the cycle continues.
