Enzymes lower the activation energy for chemical reactions, allowing the reactions to proceed. Enzymes also can serve to bring components of a reaction together in the proper orientation. Enzymes can hydrolyze macromolecules into smaller components, enabling them to be transported across the cell membrane
Answer:
In C3 photosynthesis, the reactions that require ATP take place in
B) the Calvin cycle alone.
Explanation:
In C3 PLANTS PHOTOSYNTHESIS OCCUR IN TWO STEPS-
1. LIGHT stage , WHICH TAKES PLACE IN LIGHT. In this stage water is split and ATP is released.
2. DARK stage, which takes place in dark. This the stage where calvin cycle takes place which require ATP, i.e energy. In this process sugar is produced with help of carbon dioxide. In this carbon dioxide is accepted by 5- carbon molecule ribulose-1, 5-biphosphate, which result into two molecules of 3- phosphoglycerate. this three carbon compound. hence is called as C3 pathway. hence C3 plants.
d. nitrogen cycle they are key in bacteria
The answer is <span>where plants, animals, landscape, and climate all interact.
An ecosystem involves interactions of living things with nonliving things in their environment, interactions of biotic and abiotic factors. So, biotic factors are plants, animals, and other organisms, and abiotic factors include landscape, climate, and other. Their interaction in a geographical area means ecosystem.</span>
