how do plant and animal cells get the energy out of glucose?

Photosynthesis is the process by which plants use the energy of sunlight to make sugar (glucose) from carbon dioxide and water. Respiration is the process by which animals use O2 to get energy from food.

ATP is created through a complex enzyme-driven process. There are a couple of ways this works in cells: -glycolysis, in which glucose is broken up into two subunits, called pyruvate, which creates two units of ATP per molecule of glucose. This happens in the cytoplasm, in both animal and plant cells.

The difference is that plants also have chloroplasts that perform photosynthesis. Animals get their energy by eating food, digesting it, and turning it into the base sugars, proteins, and lipids that the cells can burn to perform cellular respiration (which makes ATP).

Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don't get their sugar from eating food, so they need to make sugar from sunlight.

Through the process of cellular respiration, the energy in food is changed into energy that can be used by the body's cells. Initially, the sugars in the food you eat are digested into the simple sugar glucose, a monosaccharide. Recall that glucose is the sugar produced by the plant during photosynthesis.

This cellular respiration is carried out by every cell in both plants and animals and is essential for daily living. Cells use glucose and oxygen to produce yg p carbon dioxide, water, and energy. ... During cellular respiration, some energy is stored in ATP and some is released as heat.
472697
Glucose and other food molecules are broken down by controlled stepwise oxidation to provide chemical energy in the form of ATP and NADH. ... Cells store sugar molecules as glycogen in animals and starch in plants; both plants and animals also use fats extensively as a food store.

Photosynthesis is the process plants use to convert energy from the sun into usable energy for their cells. Plants use the light energy of the sun, carbon dioxide, and water to make glucose (a sugar), and oxygen. The energy of the sun is captured and stored in the bonds between atoms in glucose molecules.

During which stage of photosynthesis is glucose made? The Calvin cycle takes over where the light reactions end. It uses chemical energy stored in ATP and NADPH (from the light reactions) and carbon dioxide from the air to produce glucose, the molecule that virtually all organisms use for food.

Photosynthesis is the process by which green plants capture energy from sunlight and use it to make food molecules like glucose. Cellular respiration is the process used by plants and most animals, to convert the energy stored in food molecules into energy of adenosine triphosphate (ATP).

Special Structures in Plant Cells Plants make their own food in a process called photosynthesis. They take in carbon dioxide (CO2) and water (H2O) and convert them into sugars.

All organisms carry out cellular respiration in the mitochondria of their cells. They take in oxygen to convert glucose to usable ATP. In the process carbon is released as a waste. Plants and algae carry out photosynthesis in the chloroplasts of their cells.

The purpose of cellular respiration is to make energy. ... As the glucose is converted to other compounds by the cell, energy is released and can be stored as ATP. Plant cells also use oxygen to get the most energy out of glucose. Cells combine oxygen with glucose to make the products ATP and carbon dioxide.

The primary source of energy for animals is carbohydrates, primarily glucose: the body's fuel. The digestible carbohydrates in an animal's diet are converted to glucose molecules and into energy through a series of catabolic chemical reactions. Adenosine triphosphate, or ATP, is the primary energy currency in cells.

Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.
186172
Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. ... Once the sugar is made, it is then broken down by the mitochondria to make energy for the cell. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
