Catalase is an enzyme which is present in every living organism that is exposed to oxygen. Catalase's activity is affected by temperature, pH and the concentration of substrate. In catalase's case, the substrate is the hydrogen peroxide. If any of these factors change, the effectiveness of the catalase to catalyze the decomposition of hydrogen peroxide will deteriorate. If the temperature and pH change, the shape of the enzyme will change as well. This denaturation of the enzyme will obstruct the hydrogen peroxide molecules to fit in the catalase's active site.

Plants use light energy to produce food molecules during photosynthesis and obtain cellular energy from the bonds of these food molecules during cellular respiration.
The chlorophyll pigment in plants harnesses light energy to ‘manufacture’ glucose/carbohydrates which are later used by the plant for cellular respiration to power cell activities.
Explanation:
The energy from sunlight is used by the chlorophyll pigments to make ATPs through a process called photophosphorylation. In addition, the light energy is used to split water molecules into H⁺ and O²⁻. The H⁺ is then captured by NADP+ which is reduced to NADPH, while O²⁻ is evolved as oxygen. This occurs in the light stage of photosynthesis.
The NADPH is used to reduce carbon dioxide into glucose in the dark stage (Calvin cycle) of photosynthesis. Remember since this is an anabolic process ATPs (the one created through photophosphorylation) are used to power this cycle.
Excess glucose can be converted to starch and stored. Otherwise, the energy captured in the chemical bonds of the glucose are again utilized to make ATPs in cellular respiration.

Red bone marrow only differs from yellow bone marrow because of a difference in the amount of fat.
<h3>What is Bone marrow?</h3>
Bone marrow may be defined as an absorptive substance discovered in the middle of the bones. It synthesizes bone marrow stem cells and other substances which are responsible for producing blood cells.
The complete question is as follows:
- the amount of antibody
- the amount of cytokine
- the amount of antigen
- the amount of fat
Red marrow includes blood stem cells that can evolve into the different components of blood such as red blood cells, white blood cells, or platelets. While yellow marrow is constructed predominantly of fat.
Thus, it is well described above.
