What type of energy is used? Photosynthesis transforms ___________ energy into ___________ energy in ___________ molecules.

Answers

Answer:

Photosynthesis converts solar energy into chemical energy that plants use to make glucose so they can grow.

Explanation:

During photosynthesis, solar energy is converted into chemical energy in the form of ATP molecules.

----------------------------------------------------------------------------------------------

During photosynthesis solar energy is converted into chemical energy in the form of energy rich bond of ATP molecule.

ATP (Adenosine triphosphate) and ADP (Adenosine diphosphate) molecules are termed currency of energy. ADP molecule is converted into ATP molecules, whenever energy is available in certain exothermic reactions of metabolism.

ATP molecules are store- house of energy. ATP molecule is broken down into ADP molecule in presence of enzyme ATPase, releasing energy whenever energy is required.

The synthesis of ATP molecules, utilizing solar energy during photosynthesis, is termed photo-phosphorylation.

These ATP molecules produced during light reaction of photosynthesis are utilized in dark reaction of photosynthesis (Calvin cycle).

ATP molecules synthesized during photo-phosphorylation may also be used in other metabolic reactions.

Photo-phosphorylation is of 2 types, i.e. Cyclic and Non-cyclic photo-phosphorylation.

Chlorophyll molecules entrap solar energy . There are 2 types of photo systems in chlorophyll. These are photo-system -I and photo-system-II .

The electrons of chlorophyll molecule of photo-system I get excited which pass through series of electron carriers in electron transport system arranged in the order of decreasing energy level.

During the passage of electrons from carriers of higher energy level to the carriers of lower energy level, the energy is lost which is utilized for converting ADP molecule into ATP molecule.

Photo-system I is concerned with light reaction of photosynthesis only, constituting cyclic photo-phosphorylation.

The electron transport during Photo-system II results in the synthesis of NADPH2 in presence of enzyme NADP reductase. NADPH2 is used in reduction reaction of Calvin cycle.

Both Photo-systems participate in non-cyclic photo-phosphorylation that results in the synthesis of NADPH2 in addition to the synthesis of ATP molecules.

Can someone explain to me what flowering time is?? And how to control flowering time???

Answers

Answer:

Flowering time refers to the amount of time the plants will spend in the flowering stage. It begins when you switch your lights to a 12/12 schedule and ends when the buds are ready to harvest. ... In this case, the actual flowering time (as understood by most breeders) would be 2-3 weeks longer. so the flowers will spend time in differents parts of different stages

A dramatic change in the life cycle of plants is the transition to flowering, which is triggered by both environmental signals, as temperature and photoperiod, and endogenous stimuli. so it would just 2 be to watch over there environment and what u are doing 2 them

Explanation:

Answer:

Flowering time is the amount of time that a plant will stay in it's flowering stage. the flowering time of its life will reach 12 hours or less of light per day.

It's controlled by environmental conditions and development regulations, such as temperature, photoperiod and endogenous stimuli

which disease is caused when there isn't enough bile to breakdown fat and oil in food . And how is it caused​

Answers

Exocrine pancreatic insufficiency (EPI) causes problems in how you digest food. Your pancreas doesn't make enough of the enzymes that your body needs to break down and absorb nutrients. Enzymes speed up chemical reactions in your body. The enzymes made by your pancreas move into your small intestine, where they help break down the food you eat. When you have EPI, you don't get the nutrition you need because your body can't absorb fats and some vitamins and minerals from foods. You might lose weight or have pain in your belly.
